sin30
sin30 = 0.5
sin30 = 0.5
The sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right-angled triangle.
For a 30-degree angle in a right-triangle, the opposite side is the smaller side opposite to the angle, and the hypotenuse is the longest side of the triangle.
In this case, if we consider a right triangle with a 30-degree angle, the ratio of the length of the opposite side to the hypotenuse will be 1/2 or 0.5.
So, sin30 = 0.5
