# physics in trigonometry

There is definitely physics in trigonometry. The three trigonometry functions that are also used in physics are: sine, cosine and tangent also known as SOH CAH TOA, as we say in Mr.Fullerton's class. We also use the Pythagorean Theorem in physics, which is a2+ b2 = c2. We use the pythagorean theorem when we are adding vectors. In physics problems you are given the magnitude of a vector which is the hypotenuse of a right triangle and one of the angles in the triangle. You then need to determine the x and y components of the triangle. Those are the popular functions from trig that we often use in physics as well.
