The unit circle math ku answers.

In the concept of trigononmetric functions, a point on the unit circle is defined as (cos0,sin0)[note - 0 is theta i.e angle from positive x-axis] as a substitute for (x,y). This is true only for first quadrant. how can anyone extend it to the other quadrants? i need a clear explanation...

Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides: x 2 + y 2 = 1 2. But 1 2 is just 1, so: x2 + y2 = 1. equation of the unit circle. Also, since x=cos and y=sin, we get: (cos (θ))2 + (sin (θ))2 = 1. a useful "identity".
