IIT JEE Solved Problem Examples for INVERSE TRIGONOMETRIC FUNCTIONS
INVERSE TRIGONOMETRICAL FUNCTIONSIf sin q=x is a trigonometrical equation,then the value of q which satisfies this equation is denoted by sin–1 x and it is read as ‘sine inverse x’.It is called inverse function of sine.Similarly inverse functions of other trigonometrical functions are defined.Hence inverse functions of trigonometrical functions are defined.
DOMAIN AND RANGE OF INVERSE FUNCTIONSAs we know that in direct trigonometric functions,we are given the angle and we calculate the trigonometric ratio(sine,cosine,etc.)or the value at that angle.Also to many values of the angle the value of trigonometric. Inverse trigonometry deals with obtaining the angles,given the value of a trigonometric ratio.In inverse trigonometry some restrictions have been imposed on the angles, and these are based on the principle values of the angles.
