Ok let’s take this example:5 tins of soup have a total weight of 1750 grams. 4 tins of soup and 3 packets of soup have a total weight of 1490 grams. Work out the total weight of 3 tins of soup and 2 packe...

dy/dx means you have to differentiate the equation provided: y = 4x^1/2When we differentiate with respect to x we must multiply the power by the coefficient: 1/2 = power by 4 = coefficient which...

L1 ->  y = 3x – 2L2 -> 3y – 9x + 5 = 0
L2 3y = 9x − 5 L1 3y = 9x -6
Gradient is the same therefore lines are parallel.

First, make sure that the tutee understands using radians, and get them to do some examples of swapping between radians and degrees to ensure familiarity.Then explain to the tutee that they already intuit...

Taking: f(x) = (x^(2)+(3x)+1)/(x^(2)+(5x)+8)
An application of the quotient rule of differentiation is required. This rule is given as:
Where g(x) = u(x)/v(x), g'(x) = ((u'(x)v(x))...
