Express (5x + 3)/((2x - 3)(x + 2)) in partial fractions.

To start, we understand that partial fractions are used so that we can more easily integrate a function. When you add two fractions together, you consider both denominators and find the LCM ; partial fractions is working backwards from this and finding the denominators from a common multiple. The answer to the question is given as: (5x + 3)/((2x - 3)(x + 2)) = (3/(2x - 3)) + (1/(x + 2))

At each point P of a curve for which x > 0 the tangent cuts the y-axis at T, and N is the foot of the perpendicular from P to the y-axis. If T is always 1 unit below N and the curve passes through the point (1,0), find the Cartesian equation of the curve.


A curve is defined by parametric equations: x = t^(2) + 2, and y = t(4-t^(2)). Find dy/dx in terms of t, hence, define the gradient of the curve at the point where t = 2.
