integre 3*x^2
Let's compute the integral: <math><mo>∫(</mo><mn>3</mn><msup><mrow><mi>x</mi></mrow><mrow><mn>2</mn></mrow></msup><mo>)dx</mo></math> <math><mn>3</mn><mo>·</mo><mfrac><mrow><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup></mrow><mrow><mn>3</mn></mrow></mfrac></math> <math><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup></math> Indefinite integrals are defined up to an additive constant <m>C</m>, so this yields: <math><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup><mo> + </mo><mi>C</mi></math> ▷<b>Answer: <math><msup><mrow><mi>x</mi></mrow><mrow><mn>3</mn></mrow></msup><mo> + </mo><mi>C</mi></math></b><span style='font-size:smaller'>, with <m>C</m> being any constant (processing: 4 steps, 1 ms)</span>
