Firstly we want to highlight any interesting structural devices in the poem and link them to power. Shelley uses a 14 line sonnet in iambic pentameter and a regular rhyme scheme. How does this link to pow...

Square both sidesMultiply by the RHS denominator (x^2(y-2)) = y+1Expand your brackets y(x^2) - 2x^2 = y + 1Begin re-arranging towards making y the subject so moving y terms ...

Firstly, read the question a couple of times and highlight key words such as 'explain' or 'compare' to familiarise yourself with what you are being asked to do. Write some of your first initial thoughts w...

By multiplying everything in equation 2 by 2, you get 2x + 8y = 34. If you then subtract equation 1 from this you get 5y = 15. Thus y = 3, going back to equation two, and subbing y back in, x + 12 = 17, t...

First differentiate 2x² - 5x - 3 to get 4x -5. At x = 3, the gradient of the tangent must be 7, and we know it goes through (3, 0) Plug the values into y = mx + c to get the equation of the lin...
