trigonometric functions

Trigonometric functions are sinx, cosx, tanx, etc. The graph of these functions have been done in class X..

Unit Circle - The circle whose radius is 1 unit whose centre is the origin of a rectangular co-ordinate system is called the unit circle. Let q be any real number. Begin at A(1, 0) on the unit circle and measure along the circumference of arc length |l| units. If q > 0 measure the arc in the ant..
