Describe several techniques for solving trigonometric equations.

Solution

solution-: 1)To solve a trigonometric equation, use standard algebraic techniques such as collecting like terms and factoring.our preliminary goal in solving a trigonometric equation is to isolate the trigonometric function in the equation.

for example sinx= 1/2

sinx= sin pi/6

x=pi/6

Another way to show that the equation has
infinitely many solutions is indicated

sinx =1/2

Any angles that are coterminal with pi/6 or 5pi /6 will also be
solutions of the equation.
