Trigonometry: SOHCAHTOA and Special Triangles

In our last trigonometry video, we discussed SOHCAHTOA. Now we move on to a discussion of SOHCAHTOA and special triangles. Transcript: SOHCAHTOA and Special Triangles Now that we’ve introduced SOHCAHTOA, we can talk about the very important topic of SOHCAHTOA and special triangles. So this lesson will assume, first of all, that you’re familiar with […]

Coordinate Geometry: Rotations on the Coordinate Plane

This is our last video in the coordinate geometry series. Here, we will explore rotations on the coordinate plane. Transcript: Rotations on the Coordinate Plane In the previous video, I talked about reflections in the x-y (coordinate) plane. Sometimes the test also asks about rotations on the coordinate plane. In these cases, the center of […]
