Find an antiderivative of the function {{MATH_144}}.
{{CMD_145}}
Differentiate the function {{MATH_146}}.
{{CMD_147}}
Since
{{MATH_148}},
it follows that {{MATH_149}} is an antiderivative of {{MATH_150}}.
To summarize: The sum of antiderivatives is an antiderivative of a sum.
{{CMD_151}}
We have proved the following theorem.
