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.
WebTrigonometric functions don't "preserve" units. The expression under a trigonometric function must be dimensionless and so is the value of a trigonometric function. Thus, C2 in your equations is in units of frequency: Hz or 1/s. There is an error in one of the equations, perhaps a missing constant.
