Question

What is the nth derivative of sinhx and coshx?

Answer 1

The derivative of sinh(x) is cosh(x), and the derivative of cosh(x) is sinh(x)

So the nth derivative of sinh(x) is cosh(x) if n is odd; and the nth derivative of sinh(x) is sin(x) if n is even

The nth derivative of cosh(x) is sinh(x) if n is odd; and the nth derivative of cosh(x) is cosh(x) if n is even

Answer 2

Nth derivatives of cosh2x
