We started looking at some word problems with linear formulas for populations, those were fairly familiar. Looked at another problem that had both x and x+h as inputs for functions, that will lead …

We started by looking at some linear equations. One thing he did not remember was that the slope of a line perpendicular to another line is the negative reciprocal of the other line. Using …

We first looked at plotting a function. It helps to recognize the shape of the graph from the equation, but if you don't, you still move to the next steps you would even if you know the general shape- …

We started by looking at how to factor trinomials. One option is to write two sets of parentheses. From there I look first at the first term, then at the third term. And I use the middle term to guide …

We worked mostly on problems with trigonometric functions. A few involved graphing the functions. It can help quite a bit to know the shape of the graph in advance. But, if you do not, or even if you …

Worked on problems related to the early ideas of calculus today. The ideas today were closer to integration, finding an area using a summation of infinitely small rectangles using limits. That meant …
