To start off with let 2/P(P-2)=A/P + B/(P-2) making the RHS of the equation one fraction gives : (A(P-2)+B(P))/P(P-2). So now we can compare the numerators (as the denominators are the same): A(P-2)+B(P)=...

We can express sqrt(20) as sqrt (4 x 5). This is equivalent to sqrt(4) x sqrt(5). We know that sqrt(4) = 2. This sqrt(20) can be written as 2sqrt(5).

The 'm' value should be used to provide a gradient to the graph (i.e. for every 1 unit the graph moves along the x axis, its y movement will be altered by multiplying 1 by 'm'). Therefore, the higher t...

If line L is parallel to line A it will have the same gradient; in this case, the letter a in the equation y=ax+b represents the gradient. Therefore line L will be of the form y=4x+b. To find the value of...

 ∫(21x⁶-e^2x-1/x+6)dx

To tackle this question, I would do each part separately.

Firstly, take 21x⁶...using the product rule this intergrates ...
