How do you find an angle using Cosine?

Use the equation: x = cos -1 ( $$\frac{adj}{hyp}$$ ) to find the angle.

How do you find an angle using Tangent?

Use the equation: x = tan -1 ( $$\frac{opp}{adj}$$ ) to find the angle.

What is the relationship between Sine and Cosine?

sin(x) = cos(90° - x) or sin(x) = cos(π/2 - x) in radians.

What is the Tangent identity in terms of Sine and Cosine?

tan(x) = $$ \frac{sin(x)}{cos(x)} $$ .

What is the range of the Sine function?

The range of sin(x) is [-1, 1].

What is the range of the Cosine function?
