The circle whose radius is 1 unit whose centre is the origin of a rectangular co-ordinate system is called the unit circle. 1. cos q = x. 2. sin q = y. 3. tan q = y/x. 4. sec q = 1/x. 5. cosec q = 1/y. 6. cot q = x/y. The six functions of q defined by the above equation are..

Identical properties of circular functions and trigonometric functions. Let O be the origin. Let OA be the unit radius of the circle drawn with O as centre. Let OA trace an angle when OA takes the position OP. Then The tracing of the angle q and the arc AP ..

Trigonometric Ratios of Multiple and Sub-multiple Angles - The following results have already been derived under Circular function..

The six functions of q defined by the above equation are called trigonometric functions of q or circular functions of q . Now consider the unit circle of radius 1 unit. Then the circumference is 2 p . If a moving point A starts from A and travel in the counte..

Circular Permutations - When things are arranged in places along a line with first and last place, they form a linear permutation. So far we have dealt only with linear permutations. When things are arranged in places along a closed curve or a circle, in which any place may be regarded as..

Radian measure [Circular system] - A radian is the measure of an angle at the centre of a circle subtended by an arc, whose arc length is equal to the radius of the circl..
