Simultaneous equations have two unknowns, you need to find out one of the unkowns (eg. x) in terms of the other (e.g. y) in order to solve both unknowns. Using these two examples (x and y) we can construc...

The Romantics were a group of poets that were a part of the Romantic movement that marked a profound shift in sensibilities from the age of reason approach of Classicism. Looseness of form, nature, mortal...

this is implicit differentiation. We start by differentiating 3x^(2) to get 6x (lower the power by 1, multiply by the original power). For xy, we use the product rule, giving us y + (x)dy/dx (this is the ...

The body analogy is used by the Functionalists to show the way in which society functions as an organism. It argues that society is made up of various institutions that act as vital organs and enable soci...

Imagine a function f(x)=g(x)*h(x)    [that is, two functions multiplied together]

To find the derivative, f'(x)=g'(x)*h(x) + g(x)*h'(x)    

For example, f(x) = (3x²)*(cos x )     ...
