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 answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
