Firstly, to be able to find the distance between the two points we must find the y-coordinates of each point by substituting in the x values. For x=4y=3/4x4-2=1For x=8y=3/4x8-2=4Now that we know the coord...

For the first part this is a standard polynomial integral whereby we can follow the power rule for anti-differentiation. In part ii), if we look at the question we see that we're trying to get I(n-1) in o...

Start by looking for intercepts.x=0, y= 5. Therefore the curve crosses the y axis at y=5y=0, x= 5/4these are the only two intercepts. Now look for asymptotes.3. at x= 1, y becomes undefined, looking at ei...

To first find the centre of the circle, the key fact to remember is that the radius of a circle is normal (perpendicular) to any tangent. This means if you take the normals to both of these tangents at th...

Answer : 26-7iMethod : Expanding the brackets will result in the sum, 6 -15i + 8i - 20i²by assessing this you can see that you can evaluate -15i + 8i to be equal to -7i which is the imaginary p...
