To find the velocity function of a particle when given its displacement function, you must differentiate the given function. v = 6t^2 - 24t + 7 .Similarly, to get the displacement function fro...

x^{2} + y^{2} = 5 1y = 3x + 1 2Inserting 2 into 1: x^{2} + (3x +1)^{2} = 5 Expanding the brackets: x^{2}

The important concept here is that in order to add or subtract fractions, they must have a common denominator. The easiest way of finding a common denominator for three or more fractions ...

3 Mehods:Step 1: Does the function factorise. In this case yes it does. giving y=(2x+1)(x-4)Method: Find the factors of the contract in this case (4). Which are (2,2) , (4,1)We know that a quadratic must ...

(2n + 1) ^{2 }- (2n-1)can also be written be as (2n +1)(2n + 1) - (2n-1) Two brackets next to each other indicate that you must multiple them by each other, this is also known as exp...
