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...

An exemplar question is 'evaluate the strengths and weaknesses of the FPTP system'. I would prompt them to answer the question by defining the key words and giving a brief introduction. In this case it is...

Draw a free body force diagram of all the forces acting on the object.

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...
