If you look at the Taylor series expansion of e x: e x = 1 + x + x 2 /(2!) + x 3 /(3!) + x 4 /(4!)... If you then make this e ix , you get 1+ix - x 2 /(2!) - ix 3 /(3!) + x 4 /(4!)... If we split this into r...

The chain rule works so that if you have y=f(x)g(x), where f(x) and g(x) are functions of x, dy/dx = f'(x)g(x) + f(x)g'(x)

A: We might first consider the form of the poem. Does there appear to be any strict metre or rhyme scheme? No, there does not. We can however see that Eliot is toying with rhyme and metre in places, in ways ...

I would recommend analyzing on three different levels 1. word -emotive words -double meaning? 2. sentence -tenses -figurative language -sentence structure -style: informal/formal 3. text -are there any pictu...

Take for example, the equation 13a + 6a 2 = −6 rearrange the questions into the form ax 2 +bx+c=0 6a 2 + 13a + 6 = 0 method 1: cross-multiplication method you use the cross multiplication method to find the ...
