Enter any angle in degrees or radians into the calculator to determine the sin 2 theta value.

## Sin 2 Theta Formula

The following formula is used to calculate the value of sin 2 theta:

Y = Sin2(ϴ)
• Where Y is the value
• ϴ is the angle

## What is sin 2 theta?

Sin 2 theta is a mathematical operation that calculates the value of 2 times the sin of an angle denoted theta.

## How to calculate sin 2 theta?

Example Problem:

The following example outlines the steps needed to calculate the sin 2 theta value of an angle.

First, measure or calculate the angle. For this example, the angle is measured as 60 degrees.

Next, convert the angle into radians. 1 radian is equal to 57.2958 degrees, so 60 / 57.2958 = 1.0472 radians.

Finally, calculate sin2 theta using the formula above:

Y = Sin2(ϴ)

Y = Sin2(1.0472)

Y = .866
