How to set up a trigonometric equation
WebMay 9, 2024 · To model an equation, we first need to find the amplitude. A = 78 − 30 2 = 24 The clock’s cycle repeats every 12 hours. Thus, B = 2π 12 = π 6 The vertical shift is D = 78 + 30 2 = 54 There is no horizontal shift, so C = 0. WebThis creates an equation that is a polynomial trig function. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with. As a reminder, here are the trigonometric identities that we have learned so far:
