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 ...

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:

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 th...

Many organic molecules follow specific formulas to help identify them. For Alkanes this is: C_nH_2n+2 (n being the total number of carbon atoms). However, this is not the case with the...

the differential of cos(x) is -sin(x). the differential of cos(2x) is -2sin(2x). you can think of it as differentiating what is in the bracket and putting that in front of the -sin(2x). when differentiati...
