find the exact values of the sine, cosine, and tangent of the angle.
11π/12 = 3π/4 + π/6
can you please explain how to do a question like this step by step.
thank you ( i was not in school when this was done so I'm not sure how or where to start)
the two angles on the right side of the equation are unit circle angles ... you should already know the values for sine, cosine, and tangent for each of them.
plug and chug using the sum/difference identities ...
