How much is this? <br>(1/2α+1/3)²

zloy xaker [14]

Answer: 1/(4a^2) + 1/(3a) + 1/9

Step-by-step explanation:

= (1/2a + 1/3)(1/2a + 1/3)

= 1/(4a^2) + 1/(6a) + 1/(6a) + 1/9

= 1/(4a^2) + 2/(6a) + 1/9

= 1/(4a^2) + 1/(3a) + 1/9

Solve sin (x)(sin(x)-1) =0

iogann1982 [59]

Answer:

$x=n \pi$ or $x=2\pi n+\frac{\pi}{2}$

Step-by-step explanation:

The given trigonometric equation is;

$\sin x(\sin x-1)=0$

By the zero product property;

$\sin x=0$ or $\sin x-1=0$

For $\sin x=0$ , the general solution is $x=n \pi$

$\sin x-1=0$ , $\sin x=1$ , the general solution is $x=2\pi n+\frac{\pi}{2}$

Therefore the general solution is:

$x=n \pi$ or $x=2\pi n+\frac{\pi}{2}$
