Solving trig equations use both thereference anglesandtrigonometric identitiesthat you've memorized, together with a lot of the algebra you've learned. Be prepared to need tothinkin order to solve these equations. In what follows, it is assumed that you have a good grasp of the trig-ratio va...
To quickly get started on solving trigonometric identities you first need to familiarize yourself with a couple of basic identities used to derive many other complex ones. Here are some of the following basic trig identities: Note: (1 squared equals 1) ...
Plugging this definition of e raised to a complex power into the definitions of the hyperbolic trig functions in terms of e^x given above, one can easily obtain the identities sin(z) = -i sinh(iz) sinh(z) = i sin(-iz) = -i sin(iz) ...
