z = 3x(x+y)³ - x³ + 24xDifferentiating partially with respect to x and with respect to y:∂z/∂x = 3(x+y)³ + 9x(x+y)² - 3x² + 24∂z/∂y = 9x(x+y)^2<...

Furthermore, through their presentation of the divine ‘The Great Gatsby’and ‘Then We Came to the End’act as criticisms or capitalism. There is a clear correlation between the Western wor...

Integrating sin^2A and cos^2A is a bit nasty so we can use double angle formula to make it a little simpler. cos2A = cos^2A - sin^2A = 2cos^2A - 1. We can rearrange to get cos^2A in nicer terms. cos^2A = ...

We can rewrite this as (5x - 2y)(5x - 2y). Now all we have to do is expand the brackets. We can do this by multiplying all the terms in the second bracket by all the terms in the first bracket and then su...
