Consider the following example.
{{CMD_90}}
Find an antiderivative of the function {{MATH_91}} defined by expression
{{MATH_92}}, for all {{MATH_93}} in some interval {{MATH_94}}.
{{CMD_95}}
{{CMD_96}}{{MATH_97}}{{CMD_98}}
{{CMD_99}}{{MATH_100}}{{CMD_101}}
{{CMD_102}}{{MATH_103}}{{CMD_104}}
{{CMD_105}}
{{CMD_106}}
Differentiate each choice. In the last choice we get
{{MATH_107}}.
{{CMD_108}}
{{CMD_109}}
