- 11Soh Cah ToaSin of angle(θ) = "o"/h
Cos of angle(θ) = a/h
Tan of angle(θ) = "o"/a
o = opposite = b - 12Unit Circle
- 13Point (a,b) or (x,y) =(cosθ, sinθ)
unit circle intersect - 14Unit circle aboutallows us to extend the domain of sine and cosine to all real numbers
- 15domain of sine functionall of the inputs that will give a valid answer
(all real numbers) - 16range of sine function-1 <= sinθ <= 1
