Let (-5,4) be a point on the terminal side of theta

If point (-5,4) is a point on the terminal side of , then angle is obtuse (point (-5,4) is placed in the second quadrant). Consider right triangle with legs 5 and 4 and angle ( is in the first quadrant) adjacent to the leg with length 5. By the Pythagorean theorem and the length of the . Then:

1. ;

2. ;

3. .

In the second quadrant function has the same sign as in the first quadrant and functions have the opposite sign.

Therefore,

1. ;

2. ;

3. .

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
