He will be missing school tomorrow, so we went over the Law of Cosines (the topic that will be covered in class). Then, there are formulas to find the area of a triangle, one being Heron's formula (when you cannot solve for the base and height simply). I showed him a few examples, then had him do several practice problems.
Declan had trouble with Power Reducing Identities, Half Angle and Double Angle Identities. So, I showed him how to prove these specific types of problems with examples. Then, he did a few problems.
Introduction to trigonometry, right triangle trig, the unit circle, and angle of elevation. I first showed him how to approach and problem using the concepts and then had him do some practice problems.
Declan came in for a quick review before he takes the test on Saturday, and I was very impressed by how much of the information he's retained. We went through all the rules of grammar, which he had little trouble with, and did practice questions, which he did very well on. He should be in good shape.
