Introduction to Trigonometry - Math is Fun
The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle "θ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you are only given one side? Impossible? Cue sine, cosine, and tangent, which will help you solve for any side or any angle of a right triangle.
