Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. Step 4: The result obtained after the simplification will be the angle measure in radians. 1. Given an angle not in the first quadrant, use reference angles to find all six trigonometric functions. The formula is still valid if x is a complex number, and so some authors refer to the more general complex version as Euler's formula. That's nice, because then we know that all of our trig functions have a positive value and were to do a substitution of letting X equal the sign of Fatah. The trigonometric identities act in a similar manner to multiple passportsthere are many ways to represent the same trigonometric expression. Simplify[expr] performs a sequence of algebraic and other transformations on expr and returns the simplest form it finds. and convert division into subtraction each of which may lead to a simplified expression for taking derivatives. Exponents are supported on variables using the ^ (caret) symbol. Lets have a look at the examples of conversions of different angle measures. See the refine function in sympy.assumptions. Use the Pythagorean identity for sine and cosine. Exponents. In this setting, the terminal side of an angle A placed in standard position will intersect the unit circle in a point (x,y), where = and = .
