Hey yall. This is a question from my homework but it's so basic that it's just to help with the concept for me. So the question is this:
A small object A, electrically charged, creates an electric field. At a point P located 0.250 directly north of A, the field has a value of 40.0 directed to...
Actually I am unclear with your last step there. So f(h(x))h'(x) equals x, do you just plug x in for t? What if it equaled x2? Would it end up being cos x4? Hypothetically speaking.
I am in Calculus 2 and we're just reviewing calc 1. Can someone break down the concept of differentiating definite integrals for me? I am mostly struggling on the trig functions. The problem I am stuck on is
∫^{}x_{}0 cos(t^{}2) dt
