You multiply the terms of each vector that have the same unit vector (e.g. i, j, k). For example, you multiply the i terms in the first vector by the i terms in the second vector. When you've multiplied t...

A quadratic equation of the form ax^2+bx+c can be solved by factorizing the quadratic equation but before that you must check that b^2-4ac>0 so that the solution is in real numbers and not in complex n...

Revising for a Maths exam can be challenging, especially if you find yourself struggling to understand a particular topic.

One thing I would strongly recommend, from having reaped the benefits of i...

1/(√7) x(√7)/(√7) =(√7)/7

Let's use the following example: y - x = 3 y^2 + x^2 = 29 . Firstly, the second equation is the quadratic equation because it has a y-squared term. The first equation is linear because it doesn't have any...
