So we have this extra credit project dealing with second order differential equations. It is extra credit because we never covered them in class, only minor first order ones.

Then second-order schemes are derived both for scalar cases and for system cases. The errors are measured in the mean square sense. Several numerical examples are included, and numerical results ...

They are typical eighth-graders. The boys tease each other loudly. The girls draw cats on the board while they wait for the next question. The book Roberts uses: Advanced Placement Calculus.

The fundamental ideas of integration are very fully explained, the second fourteen chapters being devoted to the integral calculus and its application to finding plane areas, lengths of curves ...

THIS book gives a thorough introductory study of the properties of ordinary points in the differential geometry of curves and surfaces in 3-space. Chapter 1 gives an account of twisted curves ...
