Arcsine, arccosine and arctangent are the inverse functions of sine, cosine, and tangent. Use them to find angles based on lengths. This video shows how.

Arcsine is the inverse of the sine function. It gives you the size of an angle when you know the lengths of the opposite and the hypotenuse.

Arccosine is the inverse of the cosine function. It gives you the size of an angle when you know the lengths of the adjacent and the hypotenuse.

Arctangent is the inverse of the tangent function. It gives you the size of an angle when you know the lengths of the opposite and the adjacent.
