Solve for x within the domain ( 0< x < 2. You must SHOW ALL WORK for credit. (Hint: Use your identities to expand the expression and then
use algebra to solve for x.) (10 points)

sin 2 -

+ cos(2x) = 0

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
