I’m still working on solutions manuals for mathematics textbooks, and I’m finally working on some topics besides sinusoidal functions. Yesterday I just finished some work on an eleventh-grade solutions manual, and the topics included determining the future value of regular annuities, determining the present value of regular annuities, and creating amortization tables for savings plans and loans. Some of those problems got a little involved. Today I’m working on a much easier topic for a ninth-grade solutions manual—using points to determine the equation of a line. Today’s topic doesn’t require nearly as much thinking, so it’s a nice break for my brain.
