# Thread: Area under a graph

1. ## Area under a graph

I've been asked to find the area under a graph of a function with limits $(0\leq x \leq 2 \pi )$

I've found just one solution (the other solution turned out impossible as it was outside the limits for arcos) for a stationary point which is a local maximum, so do I just use zero as a local minimum for $x$ to find the area?

Any help is appreciated.

Hang on, do I even need to know the stationary points to find out the area? I've just drawn the graph and it looks like a "hill", a perfectly feasable graph that doesn't have any local minimums.

area under a curve involves integration ... what is the equation for the curve and limits of integration?

Hi Skeeter,

I think I'll be OK with this now, I just got a little confused remembering how to do it.

Many thanks for offering to help though.
