Final Answer: a2 +3a -18 Using FOIL (First, outside, inside, last) we multiply the terms in the brackets together. First: 3a multiplied by a = 3a2 Outside: 3a x 3 = 9a Inside: -6 x ...
y = 4x3 To differentiate you must find dy/dx. To calculate dy/dx, look at this example using just letters from algebra: y = axb dy/dx = (ab)x(b-1) As you can see, to calcu...

It is impossible to dirctly integrate sin^2(x) so we must transform it into something that can be integrated. Trigonometry can be used to do this. Recall the identity cos(2x) = cos^2(x) - sin^2(x) and cos...
This is an example of the product rule. In this, y=uv and dy/dx = u(dv/dx) + v(du/dx) u = sin2x so du/dx = 2 * cos2x = 2cos2x v = (3x-1)4 CUAnswered by Chisom U. • Maths tutor4134 Views
