I was once telling this story to John Hennessy, who is the President of Stanford University.
He started to laugh, and confirmed the story: John had been the graduate student who was kind enough to help Zeke. Zeke and I worked together on a number of problems over the years, and today I will talk about one that has a curious history, a neat proof, and a interesting application that never really happen.
Basic Math Solver offers you solving online fraction problems, metric conversions, power and radical problems.
You can find area and volume of rectangles, circles, triangles, trapezoids, boxes, cylinders, cones, pyramids, spheres.
This algorithm uses linear space: a string that starts with many ‘s will, for example, require the pushdown to hold many symbols.
Thus, the goal is to find a different algorithm that avoids using so much space.Solve your probability, combination, permutation problems. Statistics - find median, mean (arithmetic, geometric, quadratic), mode, dispersion, mormal distributions, t-Distribution.The solver successfully do Statistical hypothesis testing You can online solve chemistry equations.If your math homework includes equations, inequalities, functions, polynomials, matrices this is the right trial account. Include everything above plus finding limits (lim), sums, matrices.Solve all type of trigonometric (sin, cos, tan, sec, scs, cot) expressions, equations, inequalities. Solve integral problems - definite, indefinite integrals.The algorithm processes each input symbol as follows: If the top of the pushdown is and , then pop off the top of the pushdown; if not, then push onto the pushdown. When there is no more input symbols accept only if the pushdown is empty.The algorithm clearly runs in linear time, and it is not hard to show that it is correct.You can simplify and evaluate expressions, factor/multiply polynomials, combine expressions.You can solve all problems from the basic math section plus solving simple equations, inequalities and coordinate plane problems.His Ph D advisor was John Rhodes who is an expert on many things, including the structure of semigroups; Rhodes has recently worked on the P=NP question himself; more on that in another post.The picture is John Rhodes since Zeke is camera shy.
