Solve the equation. (Find all solutions of the equation in the interval [0, 2pi). Enter your answers as a comma-separated list.) (3 sin(2x) + 3 cos(2x))^2=9

I got

5.53+2pi times n

WORK:

Solve for x

While -1 is a solution, it isn't within the interval of 0,2pi.

However, we can use the reference angle identity

So some more possible points are

Since it on a interval, it must be less than 2 pi or 6.28.

Let find some more points

So 5.28 is a point,

That is too big since -6.28 is smaller than 7.03

We can use the identity

1 is smaller than 2pi so it is true.

Negative 3/4 is smaller than zero so it not a solution.

Make sure to include

so

We can also -3/4 plus 2 pi.

Which is about 6

5.53.

we need more info to solve this

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
