Perhaps, but I'd seem a bit illogical to do that since they said the right hand side should be tan(2x)...sighz the problem is either rather difficult or am missing a simple piece of theory to make it a 5 line proof (often the case) .

1. Given, x + yi = tan^-1 ((exp(a + bi)). Prove that tan(2x) = -cos(b) / sinh(a)Homework Equations I have derived. tan(x + yi) = i*tan(x)*tanh(y) / 1 - i*tan(x)*tanh(y) tan(2x) = 2tanx / 1 - tan^2 (x) Exp(a+bi) = exp(a) *(cos(b) + i*sin(b))[/B]3. My attempt: By...

Always been interested in math (addicted to solving problems better than cocaine!). And going to do engineering now in university, if this is actually a forum for math its the coolest thing in the world. Looking forward to working with you guys! Peace.
