Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. A basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a. The formula to convert radians to degrees: degrees = radians * 180 / π.

Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
18 lip 2024 · Solve for the sides or angles of right triangles by using trigonometry. Keep reading this article to learn more about trigonometric functions and the trig identities that relate them. The sine and cosine trigonometric functions. Trig functions are functions that take an angle as the argument.
Trigonometric Equations Formulas. We use some results and general solutions of the basic trigonometric equations to solve other trigonometric equations. These results are as follows: For any real numbers x and y, sin x = sin y implies x = nπ + (-1) n y, where n ∈ Z. For any real numbers x and y, cos x = cos y implies x = 2nπ ± y, where n ∈ Z.
