I'm interested in teaching myself Precalculus and would like to find a good book with lesson plans and assignments. Any ideas?
I have a precalculus test coming up and I'm not really understanding how to do everything. Please help. 1. Find the angle betweem 0 and 2pi which is coterminal to the angle -(7pi)/5. Now convert the angle you just found to degrees.
