Find basis for $\ker T$ with $T:P_2 \to P_2: T(p(x)) = p(x) + p(-x)$ Can you tell me clearer please :) |

find $rank(T)$ when $T: P_2\to P_2:T(p(x)) = p(x+1)$ Can you tell me, why T has that matrix representation please ? |

find $rank(T)$ when $T: P_2\to P_2:T(p(x)) = p(x+1)$ P2 is set of all polynomial that degree less or equal than 2 :) |

Modulo equation : $\frac{n^{k+1}-1}{n-1} \equiv a{\pmod p}$ Can you tell me, more, please. |

$f(1)=-3$ and $ f'(x)\geq7$ how small is $f(5)$? And. this problem is call "how small" make me think about min/max rather than think $f(5)$ is a fixed number :D |

$f(1)=-3$ and $ f'(x)\geq7$ how small is $f(5)$? ah. put your solution together with Steven Stadnicki comment to prove f(x) is a linear equation, can solve my question :D |

$f(1)=-3$ and $ f'(x)\geq7$ how small is $f(5)$? @Serkan is $f(x)$ linear, right ? But can we have this conclusion ? (I think this obvious, but maybe there some other function, that after you derive, it will be constant too) |

Multi variable integral : $\int_0^1 \int_\sqrt{y}^1 \sqrt{x^3+1} \, dx \, dy$ @Marvis region over which you are integrating is below the parabola $y=x^2$ from x=0 to 1 Could you explain more, please. |

Lagrange's method to find min/max question Sorry. Can I ask you, when I read on Wiki, constraint is an equation. and when I ask my teacher, my teacher say when constraint is inequality, we use another method. |

Lagrange's method to find min/max question can you give me an example, please. My teacher says the thing opposite :( that we can sure that no max for that function (in above example) |

Sum of two divergence series is always divergence series? @Marvis Oh. sorry so much :( I always think two examples is same :( |

Sum of two divergence series is always divergence series? Take opposite of series and plus together is too special in my opinion. |

Sum of two divergence series is always divergence series? @DavidMitra yes. I have thought your example before, but it's too special. |

Maple: how to solving composite function No. I don't think it's just for fun. it's nice. but I don't know your solution compare to first one (above post) will be same performance or not :) |

Maple: how to solving composite function Can you explain a bit at line 3 and 4,please. I know how they work, but I really don't understand why it works right. I'm thinking about your nice solution so much. Thanks :) |

Min/Max of $f(x,y) = e^{xy}$ where $x^3+y^3=16$ Oh. It likes x=y=2 case when I use Lagrange Multiplier. But at min case, I don't have any idea how to solve by Lagrange Multiplier |

Min/Max of $f(x,y) = e^{xy}$ where $x^3+y^3=16$ @N.I ah, I understand. Because I just view fomular from other post , I don't really know different $$ and $ :D |

Compute lim from Graph Can you explain why, please. I afraid that lim is 1,5 because when T= 50, it will be 0 |
