Circle Theorems

The embed below shows all 7 circle theorems. Circle theorems are a set of rules that define how circle behave and are incredibly useful to geometrical mathematics. First circle theorem - The angle subtended by a chord at the centre is twice the size of the angle subtended by the same chord at the ci…

The History of the Pulsejet

THE HISTORY OF THE PULSEJET The pulsejet is unlike any other jet engine seen before. Some versions require no moving parts, a title only previously given to rockets, which were inefficient and expensive, and ramjets, which needed to go obscene speeds to function. Pulsejet engines are characterized by…

Solving an equation by Iteration

I am solving an equation by iteration. In this case, I am going to solve x 2  - x - 5 = 0 by iteration.  First of all, I am rearranging it in the iterative form: Suppose you have to solve x 2  - x - 5 = 0 by iteration. Let's rearrange it in iterative form first. x = √(x + 5) x n+1  = √(x n  + 5) Let's ta…

Gradient of a curve by differentiation

I am finding the gradient of a curve by differentiation with the following Geogebra applet. The equation of the curve is y = x 2 /4. Gradient = dy/dx = x/2 If you move the point along the curve, you can find the gradient of the curve at any point. For example, at x = 2, dy/dx = 1
