What is the exact value of Tan 30 degrees?

What is the exact value of Tan 135 degrees?

What is the exact value of Tan 150 degrees?

What is the exact value of Tan 2Π

What is the exact value of Tan 90 degrees
 
In order to do these I'd recommend learning the sine and cosine of some specific angles:
[math]sin(0) = 0 \text{, } cos(0) = 1[/math]
[math]sin(30) = \dfrac{1}{2} \text{, } cos(30) = \dfrac{\sqrt{3}}{2}[/math]
[math]sin(45) = \dfrac{\sqrt{2}}{2} \text{, } cos(45) = \dfrac{\sqrt{2}}{2}[/math]
[math]sin(60) = \dfrac{\sqrt{3}}{2} \text{, } cos(60) = \dfrac{1}{2}[/math]
[math]sin(90) = 1 \text{, } cos(90) = 0[/math]
You can get the rest from there.

In addition to the above identities, you may need to use the following:

sin(A+B) = sin(A) * cos(B) + sin(B) * cos(A)

sin(A- B) = sin(A) * cos(B) - sin(B) * cos(A)

cos(A+B) = cos(A) * cos(B) - sin(B) * sin(A)

cos(A- B) = cos(A) * cos(B) + sin(B) * sin(A)

and corresponding formulas for tan.
