Calculus/Area
§Introduction
Finding the area between two curves, usually given by two explicit functions, is often useful in calculus.
In general the rule for finding the area between two curves is
$A = A_{top} - A_{bottom} \$ or
If f(x) is the upper function and g(x) is the lower function
$A = \int_a^b[f(x)-g(x)... |

Parallel Lines
Two straight lines, in the same plane, are said to be parallel if they do not intersect, no matter on how long they are extended on either sides.
Transversal
A straight line that intersects two or more lines in a plane is called a transversal.
When two lines m and n are intersected by line l, then th... |

# Thread: Fraction Simplification
1. ## Fraction Simplification
I want to simplify
$(\frac{2u}{v}+\frac{2u+v}{v})$
If we add the two fractions we get $\frac{4u+v}{v}$, then we can just cancel out the v in the denominator by the v term on top to get $4u$.
But apparently this is incorrect, since the correct answer h... |
