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

Examples of Kinetic Energy Kinetic energy is the energy of movement. The higher the velocity or speed, of an object, the more its kinetic energy. The heavier the object (its mass), the higher its kinetic energy. Examples of kinetic energy :1. A moving car ; 2. a moving ball ; 3. a river flowing ; 4. a plane in flight ; 5. an... More

Kinetic and Potential Energy In linguistics, the potential mood The mathematical study of potentials is known as potential theory; it is the study of harmonic functions on manifolds. This mathematical formulation arises from the fact that, in physics, the scalar potential is irrotational, and thus has a vanishing Laplacian — the... More
