Solving Trigonometric Equations

§Decide whether the
equation is linear or quadratic in form, so you can determine the

solution
method.

§If only one trigonometric
function is present, first solve the equation for that function.

§If more than one
trigonometric function is present, rearrange the equation so that one side

equals 0. Then try to factor and set each factor equal to 0 to solve.

§If the equation is
quadratic in form, but not factorable, use the quadratic formula.

Check that
solutions are in the desired interval.

sides of the equation first. If
this is done, check for extraneous solutions
