Trigonometry Examples

$(- 1, 0)$

Step 1

To find the $\cot (θ)$ between the x-axis and the line between the points $(0, 0)$ and $(- 1, 0)$ , draw the triangle between the three points $(0, 0)$ , $(- 1, 0)$ , and $(- 1, 0)$ .

Opposite : $0$

Adjacent : $- 1$

Step 2

$\cot (θ) = \frac{Adjacent}{Opposite}$ therefore $\cot (θ) = \frac{- 1}{0}$ .

$\frac{- 1}{0}$

Step 3

The expression contains a division by $0$ . The expression is undefined.

Undefined

Step 4

Approximate the result.

Undefined
