How do you use the point #(-3,-4)# on the terminal side of the angle to evaluate the six trigonometric functions?
1 Answer
The ratios tan and cot are positive, all the others are negative.
The angle we are dealing with is 233.1°
Explanation:
From the given point, we can deduce the following.
The point is in the 3rd quadrant. The right-angled triangle which is formed has a hypotenuse of length 5.
Angles in the third quadrant are from 180° to 270°.
Instead of referring to the sides as opposite, adjacent and hypotenuse, we will use them as a y-component, an x-component and the radius.
The trig ratios are as follows
In this case
