Sin Calculator

The Sine, Cosine and Tangent are the three main functionalities in trigonometry and they can be studied based on the right angled triangle. The sides of a right angled triangle is named as Opposite - opposite to the angle θ, Adjacent - adjacent to the angle θ, Hypotenuse - the longest side. Note that 'adjacent' is always the side next to the angle. Make use of the below simple sin calculator to calculate the sine of an angle in radians and degrees.

Sine (in rad) = Opposite / Hypotenuse


What is the sine of an angle 45 degrees


sin (45) = Sine values in radians is 0.85 radians and in degrees it is 0.70°

To calculate the Sine, Cosine and Tangent values follow the below rules.

sin(θ) = Opposite / Hypotenuse
cos(θ) = Adjacent / Hypotenuse
tan(θ) = Opposite / Adjacent
