For negative values of x the terms integral part or integer part of x are sometimes instead taken to be the value of the ceiling function i e the value of x rounded to an integer towards 0. Other computer languages commonly use notations like entier x int x basic ms excel or floor x c c r and python. We try to get k 1 sin 2theta k cos 2 theta. I don t like doing it with cases just because it feels to me anyway like there must exist a more condensed statement that would convey the same thing just in a more succinct way like in this case though of course such a form may.

Take the inverse tangent of both sides of the equation to extract from inside the tangent. In this case we have a square plus a number.
