Find all solutions of the equation sin^2 x=2sinx+3

Mashutka [201]

$\sin^2x=2\sin x+3$
$\sin^2x-2\sin x-3=0$
$(\sin x-3)(\sin x+1)=0$

which means either $\sin x=3$ or $\sin x=-1$ . The equation has no solution, since $\sin x$ is always bounded between -1 and 1. The second has one solution at $x=-\dfrac\pi2$ , and any number of complete revolutions will also satisfy this equation, so in general the solution would be $-\dfrac\pi2+2k\pi$ where $k$ is any integer.

So you could choose $A=-\dfrac\pi2$ and $B=2$ .

Solve and graph each of the following inequalities for x.

Ulleksa [173]

2x + 4 > 8

Step 1: Subtract 4 from both sides.

2x + 4 − 4 > 8 − 4

2x > 4

Step 2: Divide both sides by 2.

2x/2 > 4/2

x > 2

2x − 3 < 5

Step 1: Add 3 to both sides.

2x − 3 + 3 < 5 + 3

2x < 8

Step 2: Divide both sides by 2.

2x/2 < 8/2

x < 4
