Remember you can never be marked down for what you right. Time is of the essence so skip the question and come back to it. You need to identify the topic of the question and you should do everything you ...

Simply the equation. y = x√x is the same as y = x^3/2. This is because the square root of any articular number is the same as saying that number raised to the power half. Now to do x¹...

a) Integrate ln(x) by parts: u = ln(x), dv/dx = 1, du/dx = 1/x, v = x int(udv/dx) = uv - int(du/dx * v) = ln(x)/x - x so int(ln(x) + 1/x - x) = ln(x)/x - x + ln(x) + x^2 + Cb) y = ln(x)/x - x + l...

Since our function is a product of two "mini-functions" of x, we are able to use integration by parts.The trick for this is to correctly set 'u' and 'dv'. 'u' should be labelled as the function ...

Factorising is a way of simplifying an equation by putting it into common parts. In the equation above we can see that x is common to both the 5x^2 and the 20x. If we divide by x and put this in-front of ...
