Steve completed 9 homework problems in class. The function pim) relates
the time in minutes) Steve spent on his homework at home to the total
number of problems he completed. The input is the number of minutes
worked. The output is the number of problems completed.
pim)-
+ 9
Which equation represents the inverse function m(p), which uses problems
completed as the input and gives minutes worked as the output?

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
