It doesn't take much to see that science, technology, engineering and math (STEM) jobs are essential to the U.S. economy. Look at the sky-high salaries paid in Silicon Valley or in quantitative ...

The inequality will be solved when \({m}\) is isolated on one side of the inequality. This can be done by using inverse operations on each stage of the sum. The final answer is ...

In this paper we establish a uniform Harnack inequality for a class of degenerate equations whose prototype is Kolmogorov's equations in $R^3: D_{yy} u - yD_zu - D_tu ...

Show values that satisfy an inequality on a set of axes by drawing the line of the corresponding equation and shading the area specified in a question. Include a dashed line for inequalities where the ...
