Today JPaul and I reviewed some of the concepts that we've been covering lately since they can be a bit challenging. HE did a great job recalling how to do them. The first problems we practiced were giving us the coordinates of a point in the x-y plane. We plotted the point, labeled the sides and then came up with the other trig ratios. Next we were given one trig functions values and the sign of another. Using that info, we had to determine which quadrant we were in first, then we could set up the triangle to find the missing sides.
