WebNov 16, 2024 · In this section we will give a quick review of trig functions. We will cover the basic notation, relationship between the trig functions, the right triangle definition of the trig functions. We will also cover evaluation of trig functions as well as the unit circle (one of the most important ideas from a trig class!) and how it can be used to evaluate trig functions. WebThe trig functions are one of these things. With (a lot of) effort, you can show that sinx = x − x3 6 + x5 120 − x7 5040 + x9 362880 − ⋯ where the patterns of increasing the powers of x by 2, and switching between + and − signs continues forever.
