Simple physics question?

It's 3am, I've been doing homework for over 10 hours (I started after school at 4pm, only took a break for food and bathroom, seriously) and I'm brain dead

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.

    That said...

    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
