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 = ax^b dy/dx = (ab)x^(b-1) As you can see, to calcu...

Resolve the forces parallel and perpendicular to the plane.

Use the equation ΣF=ma to solve the accele...

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...
