Write-up # 1. This write-up is an examination
of Assignment 1 #3:
Find two linear functions f(x) and g(x) such that their product
h(x) = f(x) · g(x) is tangent to each of f(x) and g(x)
at two distinct points.
Write-up #3. This is an investigation
of points of concurrency of lines from the vertices of a triangle to certain
constructed points in similar figures on the opposite side of the triangle.
Write-up #4. This assignment was an
investigation of r = a + b cos(k t) for different values of a, b, and k.
This is a write-up of Assignment 12 #6. For this exploration, I boiled
water and recorded temperatures each minute for the next 30 minutes as it
cooled. Then the spreadsheet was used to plot temperature against time and
a model was fit to the data.
