# Math Help - I know how to calculate reference angles but...

1. ## I know how to calculate reference angles but...

I'm not really sure how to apply it in equations, such as:

tan(19π/6) = x

*π = pi

Do you have to find the reference angle first and then solve the equation?

Again, I was sick and absent from school for the last few days and this is one of the topics that will come on the test on Thursday.

Any help would be greatly appreciated!

2. $\frac{19\pi}{6} - 2\pi = \frac{7\pi}{6}$ , a coterminal angle.

work your solution with that angle.
