To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions.
Systems of three equations in three variables are useful for solving many different types of real-world problems. See Example \(\PageIndex{3}\). A system of equations in three variables is inconsistent if no solution exists. After performing elimination operations, the result is a contradiction. See Example \(\PageIndex{4}\).
