circular functions equations

The circular functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle contai..

1. The reciprocal of cos q = 1/cos q = sec q . 2. The reciprocal of sin q = 1/sin q = cosec q . 3. The reciprocal of tan q = 1/tan q = cot q..

\ The Circular function of a real number q and the trigonometric function for the angle q c are same. The identities for circular functions of real numbers hold for trigonometric functions of angle q..

Which of the following represents the volume V of a right circular cone as a function of the radius r of its circular base, when the height of the cone is twice the radius of the base circle? => 2 π r 3 or 1 3 π r 3 or 2 3 π r 3 or 4 3 π r 3..

With each movement the endolymph in the semi-circular canals also moves and strikes against the gelatinous material. This moves the hairs which transmit the sensation to the neurones. (i) Semicircular duct showing position of a cristae with head in still position and [ ii ] position ..

An object moving along a circular track with uniform speed is an example for a non - uniform motion because the direction of motion of the object goes on changing at every instant of tim..

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 the first or last place, th..

In the example discussed under the topic uniform and non-uniform motion we have classified motion along circular track as an example of non-uniform motion. Let us now see why circular motion is considered as non-uniform motion. The figure shows an athlete running with uniform sp..
