I like to think about the cancellation in a few more steps, however I never write it down. $$A=\pi r^2 = \pi \left ( \frac{C}{2\pi} \right )^2 = \frac{1}{4}\frac{\pi}{\pi\pi}C^2 = \frac{1}{4}\frac{1}{\pi}\frac{\pi}{\pi}C^2=\frac{1}{4}\frac{1}{\pi}(1)C^2= \frac{1}{4\pi}C^2$$

Get some study partners+whiteboards that hang on the wall. Two problems fixed then.

Coming from a guy who took the second semester of freshman physics and statistical mechanics at same time. I'd have to say it gets much harder but it's bearable. I had not had any modern physics and every other thing involved me reading a book on modern physics. Of the 5 classes I had last...

You'll be fine just work hard, your just starting.

My situation is different than most people who come to this board; I think anyways. I'm currently in my 4th year of school and can complete my mathematics degree next May. I can also choose to stay one more year and complete a physics degree on top of the math degree. However here's where I...

Thank you, sadly I won't be able to check it until i get home. On the road working.

If someone could supply the code to plot this graph in Mathematica would be awesome. Would also be best if it checked the y's at units of t {0,1,2,3...,inf} y >= 340 Plot[100 (t) - 340 (t/2), {t, 0, 20}] y< 340 Plot[100 (t) - 115 (t/2) , {t, 0, 20}]
