Chapter 6: Q. 59 (page 396)

Use the even–odd properties to find the exact value of each expression. Do not use a calculator.
$\sin (- 60^{o})$

Short Answer

Expert verified

The value can be found as $- \frac{\sqrt{3}}{2} .$

Step by step solution

Step 1. Given Information

Given that the expression is $\sin (- 60^{o}) .$ To find the value of expression using Even odd property.

Step 2. Even Odd property

The property of even odd property is $\sin (- θ) = - sinθ .$ On substituting the value,

$\sin (- 60^{o}) = - \sin 60^{o} \sin 60^{o} = \frac{\sqrt{3}}{2} - \sin 60^{o} = - \frac{\sqrt{3}}{2} \sin (- 60^{o}) = - \frac{\sqrt{3}}{2}$
