Precalculus

Welcome to Precalculus. Hopefully you saw some more advanced trigonometry using right triangles in circles. It was more complex than the right triangle trigonometry that you were introduced to in Geometry. In the first quarter most of the content will take trigonometry further. Isaac Newton back in the 1600's came up with sine or cosine wave functions to represent light waves. Later when AC electricity was invented, sine and cosine functions can be used to understand it. Physics and engineering needs to understand this level of trigonometry and then add calculus to analyze the science.

In 2nd quarter we will get closer to calculus by learning about ... If you plan to learn calculus, the subject will make it a lot easier to get started and be successful.
