x is a real number and sinh^2(x) = 24/25
a) what are the possible values of sinh(x)?
b) what are the possible values of cosh(x)?
Hello, mr_motivator!
You really don't know how to do this?is a real number and
a) What are the possible values of ?
We have: .
. . Then: .
b) What are the possible values of ?
We're expected to know the identity: .
So we have: .
Therefore: . . . (cosh is always positive.)
