WebFrom the positive x-axis, when travelling from the point (1, 0) to (0, 1) along the unit circle, we make an angle of π/2 radians (angle measure is positive for counterclockwise movement and negative for clockwise movement). Now, sin(π/2) is equal to the y-coordinate of the point (0, 1), i.e., sin(π/2) = 1. WebThe unit circle represents a complete angle of 2π radians. And the unit circle is divided into four quadrants at angles of π/2, π. 3π/2, and 2π respectively. Further within the first quadrant at the angles of 0, π/6, π/4, π/3, π/2 are the standard values, which are applicable to the trigonometric ratios.
