Alright, I have a robot. Essentially, I have motors controlling both of my wheels. My idea is to have one wheel stationary while the other wheel turns, providing a turn. That's where it gets tricky. https://imgur.com/SuFltL8 pic for reference. There is a drag stand below the board. The wheels have a radius of 1.1 inches. The distance between the wheels is 6.875 inches. I put a marker on the wheel and observed it spin 2.25 RPS (revolutions per second.) I need a function that will tell me how many seconds my wheels need to be spinning to achieve a specific amount of degrees.

Alright, say I have a string that's guaranteed to be a length that's a multiple of 4 and it only has the letters A,B,C, and D in it (upper-case). say if I had a string "ABCDDCBA" I want to make an array [ABCD, DCBA]. I'm stuck on this, I figured it looks like a nested for loop problem?

If the two microphones were at the same distance from the speaker, the two signals would be in phase: they would lie on top of each other. For the phase difference shown (90 degrees), what is the minimum distance between the two microphones?

Known values:

frequency of signals: 2000Hz

speed of sound: 328 m/s

wavelength: .164 m

phase difference: 90 degrees or 3.14 radians

Answer is 2sqr(x-4)-4arctan[(sqr(x-4))/4]

I got this from wolfram alpha, which suggests a trig substitution somewhere

I'm wearing a backless dress for my sister's wedding come up, but I'm pretty chesty, what have you found to be supportive?
