Subjunctive is a mode, a way of approaching reality. In its pure sense, subjunctive is considered as "not new information", this is, it is something you say that either describes a mental state,...

A stationary point occurs when the first derivative of the function = 0. The first derivative of f(x) is df(x)/dx = 3x^2 - 27Setting this to zero gives 3x^2 - 27 = 0 -> x = +/- 3
To find whether i...

the differential of a function y=2x^3 is the rate of change of that function. finding the differential is done by following the steps below:1) bring down the power of the x term and multiply it by the ter...

Firstly please show me what was the topic and the example in class. Given the topic I will provide the answer and the easiest way to complete it.
For example, let's say the student had to solve the ...

de Moivre's theorem gives us that (cos(x) + i sin(x))ⁿ = cos(nx) + i sin(nx), for integers n and real values x.Therefore cos(5x) + i sin(5x) = (cos(x) + i sin(x))⁵ = cos⁵(...
