trig functions helP!!

evaluate the integral of coshx sinh^2 dx limits are a=0,b=1

Notice that coshx is the derivative of sinhx so you have:
f'(x) * f(x)^2

What's the integral of something of this form?

OP

can u write the full answer plz!

can u write the full answer plz!

Try differentiating

\sinh ^3 x

by the chain rule.
You should get something that looks similar to what you're trying to integrate. You can make it exact by multiplying by a constant (constants do not affect differentiation/integration).
For the purposes of this you can think of integration as reverse differentiation, for example if you differentiate x^2 you get 2x and if you integrate 2x you get x^2.

This is how I always do these problems, it also works if you have to integrate something like

\sin x \cos ^n x

, if you differentiate

\cos ^{n+1} x

you'll get something in a similar form.
