Derivative of Tan x The derivative of tan(X) Since tan(X)=sin(X)/cos(X), we have sin(X) as the function u(X) and cos(X) as the function v(X). Putting these into the formula d[uv]/dX=(vdu/dX - udv/dX)/v2 we get d[tan(X)]/dX = (cos(X)cos(X) + sin(X)sin(X))/cos2(X) But on the top we have sin2(X)+ cos2(X), which is always 1. So our... More

Potential and Kinetic Energy All energy can be in one of two states: potential energy or kinetic energy. Energy can be transferred from potential to kinetic and between objects. Potential energy is stored energy--energy ready to go. A lawn mower filled with gasoline, a car on top of a hill, and students waiting to go home from... More
