# A-level Mathematics/Edexcel/Core 1/Differentiation

Differentiation is the opposite to integration and you use dy/dx. you drop the power in the front of the equation and you decrease the power by 1.

E.g. ${\displaystyle y=3x^{2}+4x^{5}}$ becomes

${\displaystyle {\frac {dy}{dx}}=6x^{1}+20x^{4}}$ or ${\displaystyle {\frac {dy}{dx}}=6x+20x^{4}}$

Quite easy when you know how!
