Find all solutions to the equation in the interval [0, 2īt).<br> 4) sin 2x = -sin x
Sonbull [250]

Answer:

x={0, 2pi/3, pi, 4pi/3}

Step-by-step explanation:

First, move sin x by adding sin x to both sides. sin 2x+ sin x = 0. Next using the double angle identity, sin 2x=2(sin x)(cos x), so 2(sin x)(cos x)+sinx=0. Factoring, sin x(2cos x +1)=0. Solving, sin x=0 and 2cos x +1 = 0, or cos x = -1/2.

sin x = 0. Using the unit circle, sin x=0 when x=0 and x=pi.

cosx=-1/2. Using the unit circle, cos x= -1/2 when x=2pi/3 and x=4pi/3.

How do I solve this literal equation? <br> 15 points
kati45 [8]

Answer:

\pi = \frac{A}{2r^2 + 2rh}

Step-by-step explanation:

First, we need to isolate \pi by taking it common from both terms on the right:

A=2\pi r^2 + 2\pi rh\\A=\pi (2r^2 + 2rh)

Now, since we want \pi in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with \pi on the right hand side. Then we will have an expression for \pi. Shown below:

A=\pi (2r^2 + 2rh)\\\pi = \frac{A}{2r^2 + 2rh}

This is the xpression for \pi
