Trigonometric Function and their Graphs

1. 'Sine' function→The curve of sine function passes through origin.→This function makes a sinusoidal wave in the graph. So, it is a sinusoidal wave passing through center in the graph.→The wave ...

Trigonometric Equation

We obtain expression for trigonometric functions by solving for right angle triangle drawn on a circle. Similarly, how are the expressions for the functions of the type ex - e-x^2  , 2ex +e-x , ......


If a4+b4+c4 = 2c2(a2+b2), prove that C = 45o or 135o.

    a4  + b4  +c4  =  2c2 (a2+b2)

or, (a2+b2)2  - 2a2b2  + c4  =  2(a2+b2)c2              [a2+ b2 = (a+b)2 - 2ab]

or, (a2+b2)2  - 2(a2+b2)c2   + (c2)2 =  2a2b2      

or, (a2+ b2 - c2)2 =  2a2b2      

or, a2+ b2 - c2=  2 ab
