this is part of a larger question for hyperbolic functions, but i feel if i get this the rest will come into place...what is x of tanh x= 3/4, or you can solve the below equation

3/4=(e^x - e^-x)/(e^x + e^-x)

any help is very appreciated

ok im following you all the way to the last step when you say e^x - (sq.rt.)7 = 1/2ln(7)

what makes that so? - Nov 29th 2009, 02:36 PMe^(i*pi)
