In this lesson we introduce the use of the Quadratic Formula for solving for the zeroes of a quadratic. Comparisons are made to use of Completing the Square. Applied and simplified radical expressions are practiced. You can download a copy of the worksheet used in this lesson and homework set by clicking on:

Amazing, Life Changing Tutor

Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.

We derive from first principles the main laws of rational trigonometry, using the concepts of quadrance and spread to replace the usual distance and angle. Most everything works out much simpler.

This physics video tutorial provides a basic introduction into position time graphs, velocity time graphs and acceleration time graphs – graphical analysis of linear motion. The slope of a position-time graph is equivalent to the velocity and the slope of a velocity-time graph is the acceleration. The area under the curve for a velocity-time graph…
