Equations and Definitions for Solving Trigonometric Equations with a Squared Function with the Square Root Property Trigonometric Equation:An equation consists of trigonometric functions like sin, cos, tan, etc is called a trigonometric equation.
Sin(x) = opposite/hypotenuse, cos(x) = adjacent/hypotenuse, and tan(x) = opposite/adjacent. Opposite refers to the side opposite the angle in question, and adjacent is the side adjoining the angle in question. How do you solve trigonometric equations using intervals? The first step to ...
Trigonometric equations involve the use of reference angles as well as the functions cos, sin, and tan. Unit circles, trig-ratio values, radians, and degrees also make up basic needed knowledge for solving these equations. Radical equations have radicals in them. Most people think of the radica...
