Differentiate the equation y = x^2 + 3x + 1 with respect to x.

A simple way to differentiate an equation with respect to x is to reduce each x components power by one and multiply each x component by their original power. Looking at the equation y = x^2 + 3x + 1, the co...

First of all we need to rearrange the equations in a way which allows us to get rid of either the x or y variable. To do this we need to have either the same number of x's or same number of y's in both equat...

If y = (1+3x)^2, what is dy/dx?

A good approach to solve this is to use the chain rule of differentiation. The chain rule states: dy/dx= (dy/du)*(du/dx). In this case let u = 1+3x, so y = u^2. Then dy/du = 2u and du/dx = 3, so dy/dx = (2u)...
