First you need to remember the equation area of a circle = πr² with r being the radius. Therefore as we are given the area of the cicle we need to rearrange the equation to give us the radius. ...

The system is described by a homogeneous, second order differential equation d²x/dt² +(dx/dt * c/m) + kx/m =0. First, substitute the known constants (m,k,c) to get d²x/dt<...

This model was devised by Atkinson and Shiffron and outlines the three permanent structures of memory to be the sensory register, short-term and long term memory. Each of these structures differ in their ...

Although the scene is underlined with cruelty and chaos, by the close, it marks the beginning openness and sanctity for Gloucester. There is no hope for Gloucester’s character to progress positively...

First gather all x terms on left hand side,7x²-13x-2=0.
