This calculus video tutorial explains how to solve newton’s law of cooling problems. It provides the formula needed to solve an example problem and it shows you how to derive the equation using differential equations. To is the initial temperature of the object. Ts is the surrounding temperature or room temperature. T(t) is the temperature at any time t or the final temperature of the object. The rate of cooling or the rate of change of temperature with respect to time is proportional to difference in the temperature of the object and the surrounding temperature.

Derivative of a function measures its instantaneous rate of change. It also tells us the slope of a tangent line at a point on the curve (graph of the function).

In this video we teach you how to make a simple, DIY, non newtonian fluid (Oobleck). When something is non newtonian it means it does not follow some of the laws of physics! how cool is that! HOW TO MAKE NON NEWTONIAN FLUID You will need: Corn starch food Coloring Water Thanks for watching and…

MIT grad shows how to find antiderivatives, or indefinite integrals, using basic integration rules.
