Chapter 6: Q. 71 (page 396)

Use the even–odd properties to find the exact value of each expression. Do not use a calculator.
$\tan (- π)$

Short Answer

Expert verified

The exact value for the given expression is 0.

Step by step solution

Step 1. Given Information

Given that the trigonometric expression is $\tan (- π) .$ To find the exact value of trigonometric expression using even odd property.

Step 2. Even odd property

Tangent is an odd function and it can be denoted as,

$\tan (- θ) = - tanθ = \frac{- sinθ}{cosθ} \tan (- π) = - tanπ = \frac{- sinπ}{cosπ} = \frac{- 0}{- 1} \tan (- π) = 0$
