11/27/2023 0 Comments Square root of complex number(Why this isn’t z.arg() is a mystery to me.)Īs you’ll notice, Sage is remarkably bad at doing this symbolically: it just sort of throws up its hands at 1+sqrt(3)i, where we (of course) know the answer is pi/3. The angle is the argument, so use arg(z). If we want to convert rectangular representations of complex number to polar ones, we already know how to get the length, with z.abs(). You can also use exponential (or polar) notation for complex numbers. We can get around this by using the identity above: (The “bool” means we want to know if the expression is true or false, i.e., we want a “ boolean“.) Sage (reasonably) calls this the “absolute value”: The norm of a complex number a+bi is sqrt(a^2+b^2). Lets compare coeffiecients to obtain two. Sometimes you want to extract the real part or the imaginary part of a complex number: How do you find the square roots of a complex number Lets consider the complex number 21-20i. (This choice is because “i” is often used as an index, as in “for i=1…5”.) Manipulations work as you would expect: Note that Sage uses “I” to stand for i, the square root of -1.

For example, John Wallis wrote, "These Imaginary Quantities (as they are commonly called) arising from the Supposed Root of a Negative Square (when they happen) are reputed to imply that the Case proposed is Impossible" (Wells 1986, p. 22). The imaginary number i is defined as the square root of 1. However, recognition of this fact is one that took a long time for mathematicians to accept.

The last major eye-catching update is the pair of new LED displays. The RadCity 5 Plus flew me up some super steep hills with an ease that surprised me. Rad claims a 40% increase in hill climbing speed and I believe them. I took the bike up some steep Seattle hills and the new motor worked great on both throttle-only and pedal assist riding. The new motor is lighter, smaller, better at hill climbing, and doesn’t look like such an eyesore in the rear wheel. The upside is… just about everything else. The downside is that you lose the regenerative braking option (even though that gave back only marginal battery charge). Now Rad has moved to a smaller, lighter but torquier geared hubmotor in the rear. Those were big, dinner plate-size motors that took up a lot of space in the rear wheel. The last RadCity was the final holdout in the Rad lineup for direct drive motors. The second major update that will likely catch the eye is the new motor. I’ve ridden plenty of Rad Power Bikes e-bikes and range has never been issue. It offers reasonable range of around 25-50 miles depending on if you’re ripping on the throttle or taking it easy with pedal assist. The battery is still 672 Wh, which is on the larger size of the e-bike battery spectrum. On the Step-through version, it allows the frame to be even more accessible with extra room to swing a leg through. Not only does that create a sleeker package by hiding away the battery, but it also frees up a lot more space in the triangle of the step-over frame. Just like the RadRover 6 Plus, the RadCity is getting Rad’s newly designed battery pack that slides down into the frame. The first and most obvious is a new battery. There are a pile of new updates to the RadCity that turn it into the RadCity Plus. Extras: dual displays, higher accuracy battery gauge, front and rear LED lights, 5 speed settings, half-twist throttle, higher power USB charging ports (optional), mounting for front and rear racks, fenders included standard, redesigned battery, higher torque motor.Suspension: 60 mm travel spring suspension fork with preload adjustment and lockout.Frame: 6061 aluminum, high step or step-thru.Range: 45-72 km (25-45 mi) depending on throttle or pedal assist.Or both! RadCity 5 Plus e-bike video review You can see my first ride experience on the new e-bike below, or you can keep reading for the complete run down. Both the RadCity step-over and RadCity step-through are getting a number of similar upgrades to create the RadCity 5 Plus edition. Now Rad is following a similar path with the commuter-ready RadCity e-bike line. When the new RadRover 6 Plus landed, we witnessed a slew of awesome new upgrades like hydraulic disc brakes, a new motor, upgraded display, sleeker semi-integrated battery, new lighting, and other improvements. That’s where Rad takes an existing e-bike and upgrades the quality and utility of the bike by adding new features and higher spec components.Įarlier this summer we saw Rad Power Bikes do something similar with its most popular e-bike, the fat tire RadRover. The new RadCity 5 Plus is the latest e-bike in Rad’s lineup to get the “Plus” treatment. The team at Rad kindly gave me the opportunity to get an early test ride on the new RadCity 5 Plus, and today I’m taking you along with me to see what makes this new e-bike tick. The RadCity 5 Plus e-bike from Rad Power Bikes has just been launched with a pile of new upgrades, making it the most extensive update to the RadCity electric commuter e-bike yet. 11/25/2023 0 Comments Fantavision video gameRidge Racer Revolution (1995 - Japan, 1996 - USA/EU), for PlayStation.Ridge Racer 2 (1994 - worldwide) for arcades.Ridge Racer (1993 - worldwide PS port 1994 - Japan, 1995 - USA/EU), for arcades and the PlayStation (launch title).The mascot of the series is the fictional idol character Reiko Nagase, who occasionally cameos in Namco's other games. Unbounded toned down the drifting in favor of large-scale destruction. Starting with the PlayStation Portable games, Ridge Racer began to focus on flashy, hyper-unrealistic drifting braking is made obsolete as the game locks you to the track when drifting. Even the soundtrack is made in-house, atypically for racing games. Ridge Racer takes place in its own fictional universe, dubbed "Ridge City", complete with its own fictional line of cars and in-game brands (many of which are named after other Namco games). An eighth game, dubbed Ridge Racer Unbounded, was released in 2012 and developed by Bugbear Entertainment (developers of the first two FlatOut games). So far, seven official games have been released, mostly on the PlayStation. It's become a tradition for a new PlayStation console to have a new Ridge Racer game as a launch title, and the 3DS, DS and Xbox 360 were launched with one as well. They found greater popularity on the PlayStation, where the first Ridge Racer game was announced as a launch title, owing much of its success to its emphasis on fast-paced racing over super-realism.

I can ctrl+alt+del, but any option I then click does nothing. The windows login allows me to set a password and login, but instead of the desktop gives me a light blue screen where I can't do anything. Tried to go through the install disk to Command Prompt > regedit and disabled all the setup values. The server says that it can't complete installation in safe mode. It just keeps doing the little animation forever. When I try to install an OS (Windows Server 2008 R2) it does all its installing, reboots a couple times and then gives the "Setup is preparing your computer for first use" screen.

NASAs Perseverance rover will look for signs of past life in a region of Mars where the ancient environment is believed to have been favorable for microbial life. The map also shows the location of the Mars Helicopter. Several other users on different social media platforms have also shared the same video with a similar claim.
