The quick answer is that d/dx a^x = ln(a) * a^x. But why?
Well, let's go through the steps so we can understand why the formula works.
Firstly, a^x can be written as (e^(ln(...
We are tasked with differentiating y = sin(x2)ln(5x)This function is actually a product of the functions:sin(x2) and ln(5x)Therefore the product rule will be re...
Solving cubics is an interesting problem: while there is a formula which can find the roots of every cubic equation, it isn't taught and is not generally worth learning. Instead, exam questions will of...
We recall that a function f(x) is said to be an odd function when f(-x)=-f(x).
We are told that f(x) and g(x) are odd functions, so we know from the abov...
