The very first step in solving this problem is understanding that a stationary point is where the derivative of the curve, dy/dx (or in Newton’s notation y’), is equal to zero. This is because at stationa...

One of the main aims of Lloyd George’s post war coalition government was to create a ‘land fit forheroes’; a Britain that troops coming back from the war could be proud of as a reward for and demonstratio...

When discussing the person of Jesus one can consider three interpretations: Jesus as the son of God,(regarding his divine nature, his knowledge of it and how it impacted other aspects of his personality),...

Quotient rule: d(u/v)/dx = [(du/dx)v-u(dv/dx)]/v^2
u = ln(3x)
v = e^4x
Find du/dx using chain rule:
u = ln(z) ==> du/dz = 1/z
z = 3x ==> dz/dx = 3
(du/dz)(dz/dx) = ...

A countries dependency ratio is the total elderly population (65 years old +) divided by the total working age population (15-65 years old) times by 100. An ageining population would create a high percent...
