Basic Sine Ratio
Calculate the sine of an acute angle in a right triangle.
sin θ = Perpendicular / Hypotenuse
Formula Explanation
Sine is the ratio of the opposite side to the hypotenuse.
Variables Explained
θ = Angle; Perpendicular = Opposite side; Hypotenuse = Longest side.
Solved Example
If the opposite side is 3 and hypotenuse is 5, find sin θ.
sin θ = 3/5 = 0.6.
