Differentiating cosh

[sapphyr_raven]

Differentiate the following with respect to x: cosh(5x^2+2x)


l get 10x+2(sinh(5x^2+2x))

ls that anywhere near right? I can't find any examples that are similar in my textbook.

Please help. Thank you.

Hello, sapphyr_raven!

Differentiate the following with respect to x: .f(x) = cosh(5x^2 + 2x)

l get: .(10x+2) sinh(5x^2 + 2x)

Your procedure is correct . . . don't forget those parentheses.
