A {{CMD_105}} computes signed area: {{MATH_106}} Here we always have limits of integration, both of which are numbers. Moreover, definite integrals have definite values, the signed area between {{MATH_107}} and the {{MATH_108}}-axis. Pay attention to the notation: {{CMD_109}} {{ENV_110}} {{CMD_111}} Where {{MATH_112}}. {{CMD_113}}{{COMMENT_114}} Definite integrals {{CMD_115}}{{CMD_116}}have{{CMD_117}}{{CMD_118}}do not have{{CMD_119}}{{CMD_120}} limits of integration, and they compute {{CMD_121}}{{CMD_122}}signed area{{CMD_123}}{{CMD_124}}an antiderivative{{CMD_125}}{{CMD_126}}a class of antiderivatives{{CMD_127}}{{CMD_128}}. {{CMD_129}}
