in section eight-five

you have to check to see if your problem is has the same inverse if it does not the you have to use the identities that you learn in eight-four to get the same trig function.
(hints: you can not try to make it or tan or cot by sin over cos or cos over sine.

after you you follow the inverse rules

THINGS YOU CAN NOT DO!
you can not divide by a trig function when solving to cancel.
you also can not cancel from the inside of a trig function.

example

4 sin(squared)(theta)=1

you have to move the 4 to the other side equal side

sin(squared)(theta)=-1/4

then you have to take off the squared so you squared root both sides of the problem

sin(theta)=plus or minus squared root 1/4

you move sin over and make the sin an inverse

theta=sin(inverse)(squared root 1/4)
when you put in your calculator it equals to = 25 degrees.

then you graph it on the y-axis and x-axis
