Trigonometric functions, identities, formulas and the sine and cosine laws are presented.

An identity is a statement which says two quantities are equal, like as x + y = y + x or sin (x + y ) = sin x cos y + cos x sin y. If we take complex numbers and using the de moivre's identity which reads. There are only three, basic pythagorean identities, the other forms. So that is my humble question. They also show that the graphs of sine and cosine are identical, but shifted by a constant of.

Sinx = cosx tanx cosx = sinx cotx. This makes it essential to know in which quadrant the angle x lies so that it can be determined if the value of sin x is positive or negative.
