6 circular functions

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..

Many of iron containing enzymes take part in electron transfer in both photosynthesis and respiration. 4. Structure of polyribosome..

Function - Any relation on A x B in which (i) no two second elements have a common first element and (ii) every first element has a corresponding second element is called a function.Any relation on A x B in which (i) no two second elements have a common first element and (ii) ev..

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 th..

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 ..

Organic compounds having same molecular formula but different functional groups exhibit functional isomerism. For e.g., ethanol (C 2 H 5 OH) and methoxy methane (H 3 C-O-CH 3 ) have the same molecular formula C 3 H 6 O. But the functional group in ethanol is..
