In this video we are going to discover what simultaneous equations are, and how to solve them. Simultaneous equations are two or more equations with two or more unknowns. They are called simultaneous because they must be solved at the...

The video is a lecture presentation about the nitrogen cycle and how the essential element is continuously recycled in nature. The speaker first explains the concept of cycles in general and why they are necessary due to the finite...

The video is a lecture presentation on sketching higher order polynomials. The presenter begins by recapping the general trends for even and odd powered graphs. Then, they introduce a general strategy for sketching any higher order...
