The first step to solving this is equation is to notice that the equation is of a similar to the form of a quadratic equation: ay^2 + by + c  = 0 where a, b and c are constants. Next we introduce a new va...

Let u = x²+4x+2 so y = ln(u).

Then dy/du = 1/u and du/dx = 2x+4.

Using the chain rule we have:

dy/dx = (dy/du)*(du/dx)

= (1/u)*(2x+4)

= (2x+4)/(x²+...

The first stage is lexical analysis which takes the source code as an input and: • Removes whitespace and comments; • Converts remaining code into tokens, by breaking down the code by recognising reserved...

In order to find the nth term of a sequence you need to keep the structure of the nth term sequence in mind (dn+x). The first thing we want to do is find 'd'. In this case 'd' stands for difference, which...
