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 ...
Carpathian Journal of Mathematics, Vol. 30, No. 1 (2014), pp. 15-22 (8 pages) In this paper, by using a simple technique, we obtain several existence results of the solutions for general variational ...
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that ...
