y = Sin(2x)Cos(x). Find dy/dx.

Assume base differentiation knowledge: Sin(x) = Cos(x), Cos(x) = -Sin(x)The question combines the chain and product rule. To begin, start by splitting the equation: Sin(2x)Cos(x) = Sin(2x) x Cos(x)The pro...

How would I write (1+4(root)7)/(5+2(root)7) in the form m + n(root)7, where m and n are integers?

We know that any value divided by itself is equal to 1, therefore we can multiply the value in the question by (5-2(root)7)/(5-2(root)7) and the value would not change. We are only changing the values for...
