My assignments

Overview:

In assignments 1-3, we explore sine functions and quadratic functions.

In assignments 4 and 6, we explore the medians of a triangle, the centroid, and the triangle constructed by the medians of a given triangle.

In assignment 8, we explore the orthocenter of a triangle and the ratio of line segments on the lines containing the altitudes, divided by the orthocenter.

In assignment 9, we explore pedal triangles when the pedal point is on one of the centers of a given triangle.

In assignment 7, we explore tangent circles.

In assignment 5, I listed a few useful GSP script tools for constructing diagrams.

In assignment 10 and 11, we explore parametric equations and polar equations.

In assignment 12, we explore the Fibonacci Sequence using the spreadsheet.
