Trigonometry Equation Formula PDF
- TRIGONOMETRIC EQUATION:
An equation involving one or more trigonometrical ratios of unknown angles is called a trigonometrical equation
- 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.
