Precalculus

We mostly looked at functions with polynomials that had asymptotes and holes. One polynomial had the form of a sum of two cubes, where knowing a related formula is helpful. To get the coordinates of …

We mostly looked at hyperbolas. For the equations, one term (x or y squared) is positive and the other is negative. The graph will be either vertical for positive y or horizontal for positive x. h,k …

We started by looking at arithmetic and geometric sequences and sums. Arithmetic is more like addition, geometric has more to do with multiplication. Subscripts are used as labels. If the number is …

We started with some problems involving logarithms and natural logarithms. By acting the log function on something with an exponent, the exponent can be brought in front. Continuous compound …

We started by looking at some problems with division of polynomials. Chose to use synthetic division, long division would be an option also. To fully factor, for example, a fourth degree polynomial, …

We started with some problems involving bearings. The direction can get mixed up pretty easily, but the problems were fairly straightforward. Another problem asked for the exact value of cos 255 …
