When would you apply the product rule in differentiation and how do you do this?

The product rule is used to differentiate a function when it is in the form y= u(x)v(x). To use the rule you differentiate u(x) and multiply that by v(x), and then add that to the differential of v(x)...

A curve has the equation y=12+3x^4. Find dy/dx.

Bring the power down and multiply it to the value directly before x, and then remove 1 from the power after this. So in this instance 12 has no x or power with it, therefore it disappears because you mult...
