Number Theory - Proof of divisibility by $3$ Yes i do that if x = y(mod3) then x and y divide 3? |

Injective and Surjective Functions thanks. it makes sense to create a proof that includes all possible cases. |

Injective and Surjective Functions I edited my proof for a. Please confirm that this is valid. |

Evaluate $\int \cos^3 x\;\sin^2 xdx$ integral cos^3(x) sin^2(x) dx = 1/30 sin^3(x) (3 cos(2 x)+7)+constant |

Equivalence Relations How would I refer to the ordered pairs then? |

Equivalence Classes I proved it by showing R to be reflexive, symmetric, and transitive. I just don't have much experience with equivalence classes. |

Equivalence Classes I concur. I probably should have been more specific and noteed that I had already proven that R was an equivalence relation. |

Equivalence Classes thanks. so the equivalence class would be the set of all odd integers. |
