#### Explanation:
Then we apply the 'radical rules':
$\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}$ and $\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}$

# Maths - Cubic Functions
A cubic function has an x3 term, its general form is:
a x3 + b x2 + c x + d = 0
The three solutions are:
root1 = -a/3 + ((-2a3 + 9ab - 27c + sqrt((2a3 -9ab +27c)2 + 4(-a2 + 3b)3))/54)1/3 + ((-2a3 + 9ab - 27c - √((2a3 -9ab +27c)2 + 4(-a2 + 3b)3))/54)1/3
root2 = -a/3 - (1 + i sqrt(3))*0.5*(... |
# Derivative and operations
Algebraic approach to derivatives requires two components. The first is elementary derivatives, which are the basic building blocks from which we will construct derivatives. The second ingredient is grammar, rules by which we put together the elementary derivatives. In other words, we need ... |
