Solving Trig Equations

Today we did some more trig equation examples from an acceleration math sheet. I understood how to evaluate the questions. I leaned that the 30, 60, 90 triangle is always on the outside values on the unit circles and the 45,45,90 triangles are aways on the values in the middle. For example 45 degrees is a 45, 45, 90 triangle and the two surrounding values, 60 and 30 are 30, 60, 90 triangles. First eight questions on exercise 4 are due.
