It describes the differential survival and reproduction of different organisms with varying phenotypes. These differences are at least partially heritable, thus over time, gradual changes accumulate in a ...

The moment of a couple is the force times the perpendicular distance between the lines of action of the force.

Horizontal: T1 sin θ1 = T2 sin θ2Vertical: T1 cos θ1 + T2 cos θ2 = w

A stationary point is a point where dy/dx = 0.First we need to find dy/dx. This is done by differentiating y term by term to get dy/dx = 3x^2 - 6x - 9.Setting this equal to zero, we need to solve 3x^2 - 6...
