Find the area bounded by the curve x^3-3x^2+2x and the x-axis between x=0 and x=1.

To find the area under a curve that is bounded by the x-axis you simply need to integrate the equation of the curve between the limits, so for this equation we will integrate y=x 3 -3x 2 +2x with 1 as our up...

Differentiate ln(x^3 +2) with respect to x

The differential of ln(x) is x^-1 or 1/x. Because we have x^3 + 2 inside the bracket we have to differentiate this term also and multiply this with the other term. For example, d/dx of x^3 +2 is equal to 3x^...

A curve is defined by the parametric equations: X = 3 – 4t , y = 1 + (2/t) Find (dy/dx) in terms of t.

When dividing fractions by fractions with a common factor: (a/c) / (b/c) = (a/c) * (c/b) = (ac/bc) we can cancel the common factor to get (a/b). So in this question we can do the same: (dy/dt) / (dx/dt) = (d...

What is the photoelectric effect?

The photoelectric effect refers to the emmision of electrons from a surface, usually a metal, as a result of shining light (EM radiation). The light is absorbed by the electrons on the surface and thus the e...
