Calculate sin−1
x= opposite_side/hypotenuse
sin−1(x)
_
Inverse Sine sin−1() is used to find the angle for a given ratio of the length of the opposite side to the length of the hypotenuse, in a right angled triangle.
Formula
To find the Inverse Sine of a given ratio: opposite_side/hypotenuse , use the following formula.
θ = sin−1(Length_of_Opposite_side / Length_of_Hypotenuse)
