If the object is speeding up, then its acceleration is directed in the same direction as its motion, this means that the object has _________ ________

positive acceleration? lol gl.

for the derivative thing i'm sure if u expressed cot and sec as cos and sin a bunch of them will cancel out.

Wow. If your hw takes you more than 10 hours, I don't think it's worth doing all of it.

positive velocity? I'm not sure what kind of answer the question is asking for.

So, multiplying it out:

cosx/sinx * 1/cosx * sinx * sinx = sinx

derivative of sinx is cosx.

(I'm assuming that sin^2x means (sinx)^2
