First we need to simplify each term:
So we will have:
Since we have the value of, we can divide the numerator and denominator by.
We can then substitute the value ofin the obtained function.
Example Question #2 :Trigonometric Equations
A right triangle has an angle of. If the side opposite it has a length of, what is the hypotenuse?
For this problem we will use the sine function as.
Plug in our given information:
Example Question #1 :Trigonometric Equations
A right triangle has an angle of. If the side adjacent to it has a length of, what is the hypotenuse?
For this problem we will use the cosine function as.
Plug in our given information:
Example Question #4 :Trigonometric Equations
In a right triangle, if
and
then what doesequal?
One can draw a right triangle with acute anglesand. The side adjacent tois 4, and the side adjacent tois 3.
Example Question #1 :Solving Trigonometric Equations
If, find the value of the function.

We can write:
We can also write:
Now we can substitute the values of (sinx - cosx) and (sinx * cosx) in the obtained function:
