A Half Angle Formula Calculator helps you quickly and easily find the sine, cosine, or tangent of half an angle in trigonometry. Ever wondered what happens when you cut an angle in half? That’s where half-angle formulas come in! Let’s make this math magic simple and fun to understand.

## The Half Angle Formula

The half angle formula finds the sine, cosine, and tangent of an angle half the size of another. It’s super useful for angles to measure or calculate directly. By splitting a big angle into half, we make our calculations easier and get precise results faster.

*sin(θ/2) = ±√[(1 – cos(θ))/2]**cos(θ/2) = ±√[(1 + cos(θ))/2]**tan(θ/2) = ±√[(1 – cos(θ))/(1 + cos(θ))]*

## Example of a Half Angle Formula?

Think of it like cutting a pizza slice in half:
