Trig Cheat Sheet Definition of the Trig Functions Right triangle definition For this definition we assume that 0 2 p <<q or 0°<q<°90. opposite sin hypotenuse q= hypotenuse csc opposite q= adjacent cos hypotenuse q= hypotenuse sec adjacent q= opposite tan adjacent q= adjacent cot opposite q= Unit circle definition For this definition q is any ...
For this definition θ is any angle. The domain is all the values of θ that can be plugged into the function. 1 tanθ , ⎛ θ ≠ ⎜ n + ⎞ ⎟ π , n = 0, ± 1, ± 2, ... ⎝ 2 ⎠ cscθ , θ ≠ n π = ± ± , n 0, 1, 2, ... secθ θ ≠ ⎛ 1 ⎞ , ⎜ ⎝ n + ⎟ π , n = 0, ± 1, ± 2, ... θ cotθ , ≠ n π , n = 0, ± 1, ± 2, ... f ( θ ) . So, if ω is a fixed number and θ.
