Simultaneous Linear Equations
Simultaneous linear equations in two variables involve two unknown quantities to represent real-life problems.
It helps in establishing a relationship between quantities, prices, speedtime, distance, etc results in a better understanding of the problems.

1. ## surface area about x-axis
I need to find the surface area of the above curve, about the x-axis. I'm having trouble taking the integral. Once everthing is set up its:
$2pi\int(\sqrt{x})(\sqrt{(1+(1/4x)^2))}$ from 4 to 9
Or at least, that's what I think it is..
Any help would be greatly appreciated.

# Acceleration
(Redirected from Deceleration)
In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law.[1] The SI unit for acceleration is metre per second squared (m... | {} |
# connection between discrete valuation rings and points of a curve.
Let $C$ be a projective irreducible non-singular curve over a field $k$ and let K be its function field. It applies that $(k[X,Y]/I(C))_{(X-a,Y-b)}$ (i.e. the localization of $k[X,Y]/I(C)$ at $(X-a,Y-b)$) is a discrete valuation ring w.r.t. $K$ and $... | {} |

In a nonabelian setting the correct notion of kernel is given by the kernel pair, and the correct notion of cokernel is given by the cokernel pair. For example, in any category, a morphism $f : a \to b$ is a monomorphism iff its kernel pair exists and is trivial, and dually $f$ is an epimorphism iff its... | {} |
