Simplify $$\tan x \times \text{cos} x$$

$$\tan x \times \text{cos} x = \text{sin} x$$

Simplify $$\text{sin} x \times \text{csc} x$$

$$\text{sin} x \times \text{csc} x = 1$$

What is the relationship between secant and cosecant?

$$\text{sec}x = \frac{1}{\text{cos}x}, \text{csc}x = \frac{1}{\text{sin}x}$$

Simplify $$\text{cot} x \times \text{sec} x$$

$$\text{cot} x \times \text{sec} x = \text{csc} x$$

What is the co-function identity for sine and cosine?

$$\text{sin}(\frac{\text{pi}}{2} - x) = \text{cos} x$$

Simplify $$\text{sin}^2 x + \text{cos}^2 x$$

$$\text{sin}^2 x + \text{cos}^2 x = 1$$

What is the definition of cosine?

$$\text{cos}x = \frac{\text{adjacent}}{\text{hypotenuse}}$$

Simplify $$\text{sec}^2 x - 1$$

$$\text{sec}^2 x - 1 = \tan^2 x$$

What is the definition of cotangent?

$$\text{cot}x = \frac{\text{cos}x}{\text{sin}x}$$

Simplify $$\text{sin} x \times \text{sec} x$$

$$\text{sin} x \times \text{sec} x = \tan x$$
