4-87.

Given cot

*β*=and *β*is in Quadrant III (<*β*<), find the following values. Try drawing a triangle where cot *β*=and find the missing side. Next determine if the value you are finding is positive or negative based on the location of the angle. Homework Help ✎ cos

*β*csc

*β*

What must the signs be for

the coordinates in Quadrant III?

Find the missing side. Note: The hypotenuse is always +.

Find the cos β.

Follow a similar thinking process as in (a).
