The figure is a unit circle, with origin O as centre cuts the x-axis at A (1,0) and let a variable point moving on the circumference move through an arc length q . i.e., AP = p( q ). The coordinates at the position of p( q ) are p(x,y) = (cos q , sin q ). Then the tangent function is defined ..

When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m AOB. An angle is measured in degrees,..

"The point of concurrency of the angle bisectors of the angles of triangle, is called the incentre". It is abbreviated as 'I'. To determine the incentre of a triangle, it is just sufficient to find the point of intersection of its two angles. The third angle bisector is bound to pass through it by ..

A function f(x) is called periodic if there exists a non zero number p such that f(x+p) is defined and f (x+p) = f(x) for all values of x in the domain of f(x). The number p is called the period of f(x). The function sinx has periods 2 p , 4 p ,6 p ,....since sin (x+2 p ), sin (x+4 p ), sin (x+6 p..
