In Problems 35鈥� 44, solve each equation. Give a general formula for all the solutions. List six solutions
$\sin \frac{胃}{2} = - \frac{\sqrt{3}}{2}$

Short Answer

Expert verified

A general formula for all the solutions is $\{胃 | 胃 = \frac{8 蟺}{3} + 4 苍蟺, 胃 = \frac{10 蟺}{3} + 4 苍蟺\}$ and list of six solution of the given equation is $\{\frac{8 蟺}{3}, \frac{10 蟺}{3}, \frac{20 蟺}{3}, \frac{22 蟺}{3}, \frac{32 蟺}{3}, \frac{34 蟺}{3}\}$ .

Step by step solution

Step 1. Given Information

In the given problems we have to solve each equation. Give a general formula for all the solutions. List six solutions.

$\sin \frac{胃}{2} = - \frac{\sqrt{3}}{2}$

Step 2. The period of the sine function is 2π.

In the interval $[0, 2 蟺)$ , the sine function equals $- \frac{\sqrt{3}}{2}$ at $\frac{4 蟺}{3} or \frac{5 蟺}{3}$ .

To find these solutions, write the general formula that gives all the solutions.

role="math" localid="1646756713050" $\frac{胃}{2} = \frac{4 蟺}{3} + 2 n 蟺 or \frac{胃}{2} = \frac{5 蟺}{3} + 2 苍蟺 \frac{胃}{2} 路 2 = 2 路 (\frac{4 蟺}{3} + 2 苍蟺) or \frac{胃}{2} 路 2 = 2 路 (\frac{5 蟺}{3} + 2 苍蟺) 胃 = 2 路 \frac{4 蟺}{3} + 2 路 2 苍蟺 or 胃 = 2 路 \frac{5 蟺}{3} + 2 路 2 苍蟺胃 = \frac{8 蟺}{3} + 4 苍蟺 or 胃 = \frac{10 蟺}{3} + 4 苍蟺$

Step 3. The general formula is θ=8π3+4nπ or θ=10π3+4nπ

We find the six solutions by putting $n = 1, 2, 3, . . . . . . . .$ in general formula

Six of the solutions are

$\{\frac{8 蟺}{3}, \frac{10 蟺}{3}, \frac{20 蟺}{3}, \frac{22 蟺}{3}, \frac{32 蟺}{3}, \frac{34 蟺}{3}\}$
