Question

Use the given function value and the trigonometric identities to find the exact value of each indicated trigonometric function.

sin(30°) = 1/2
,
tan(30°) = 3/3

(a)    csc(30°)

 

(b)    cot(60°)

 

(c)    cos(30°)

 

(d)    cot(30°)

 

Answer 1

I will not do this for you, but I will remind you how to do it.

In a 30-60 right triangle, the hypotenuse is 2, the shorter leg is 1 and the longer leg is √3.

Draw a figure and label it.

Then use the definitions of the trig functions to get your answers.
