Answers

Answered by mramansingh044

Start measuring the angles from the first quadrant and end up with 900 when it reaches positive y axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. Therefore Sin 90 degree equals to the fractional value of 1/ 1.
