So,
Finding problems such as "x is 10% of y" and solving them is really easy: simply multiply the number you are given by 10 to get 100% of that number.
3.3 * 10 = 33
The number you are looking for is 33.
Start by getting everything on the same side of the equals sign and then set it equal to 0.
. Factor out the common tan^2x like this:
. Now we have 2 separate equations to solve:
and sinx = 0. Now we have to figure out where tan^2 is 0 between 0 and 2pi. If we include 2pi, the solutions for that equation are
. You can test those out on your calculator just to be sure. There's only one value of x for the next equation. The only place between 0 and 2pi where the sin x = 1 is at x =
. And there you go!
Tricky question. What are you trying to figure out?
