Yeah, I knew that sec(x) = 1/cos(x) and I still couln't figure out what to do

Homework Statement Let h(t) = tan(3t+7) Find h'(t) and h''(t) I found h'(t) which is equal to 3(sec(3t+7))^2 But I can't seem to find h''(t) How do I find the derivative of this? Could someone please teach me? Is it a composition function? If it is, I think I see 4 functions...

Could you please tell me how you got the blue part? I put it in and it's still wrong :(

Homework Statement Let f(x) = sqrt(sin(e^(x^4*sinx))) Find f '(x) I tried this many times and it's really frustrating! I made it a composition function : f(g(h(x))) but I'm not getting the answer at all. At the end, I found : 1/2(sin(e^((x^4)(sinx))))^(-1/2) (cos(e^(x^4...
