The area under a curve can be estimated by dividing it into triangles, rectangles and trapeziums. If we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding the ...

Sufficient conditions are obtained for a function harmonic in the disk and continuous at a boundary point to have a level curve emanating from the boundary point into the disk. The one-sided ...

Scatter graphs are used to represent and compare two sets of data. By looking at a scatter graph, we can see whether there is any connection (correlation) between the two sets of data. Matt sells ...
