b. what does d/dx[cosh u] equal ?
c. what does d/dx[tanh u] equal ?
d. find the derivative of the function y=sech(4x+2) using substitution. cite any formulas you use

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )
