It's been a while, but I think "integration by parts" is what you seek finding definite integral between 2 x values using anti derivatives is what I am doing. My book is traded and my professor doesn't give a fuck about actually helping anyone. That tenure thing.... |

Am I the only who gets pissed at bs like sqrt(4-x^2)? That trolling got fucking old in Algebra. Yet they still pull that shit in Calculus. You're not fooling anyone. Business major? Use Paul's Notes: http://tutorial.math.lamar.edu/Classes/CalcI/CalcI.aspx . That's about the limit of my sympathy for a student without a text book. |

It's called integration by substitution.
Set u = 4 - x^2 So: du = -2x Multiply the original first term by -2 * -1/2 (i.e. "multiply by 1") to get S -2 * -4/2 * x * (4 - x^2)^1/2 dx Sub in your u and du terms to get S -4/2 * u^1/2 du which I know you know how to solve. Integrate, replace your u term with the x variable, then calculate the value of the formula. Do your own homework with the information above. |

I raised to a -1/2 power instead of a positive 1/2. ARFCOM fixing the worlds problems one at a time

Is this for Cal 1, 2, or 3? Edit: Jesus, I just went through all my Cal 2 notes and now I want to stab myself... |
