  1. TRIGONOMETRIC EQUATION:

An equation involving one or more trigonometrical ratios of unknown angles is called a trigonometrical equation

 

  1. SOLUTION OF TRIGONOMETRIC EQUATION:

A value of the unknown angle which satisfies the given equations is called a solution of the trigonometric equation.

(a)     Principal solution: the solution of the trigonometric equation lying in the interval [0, 2n].

(b)     General solution: since all the trigonometric functions are many one & periodic, hence there are infinite values of  for which trigonometric functions have the same value. All such possible values of  for which the given trigonometric function is satisfied is given by a general formula. such a general formula is called general solutions of trigonometric equation.
