calculate the volume of a zone Thank you for your answer. However, is there any more "standard" way to reach the answer? The polar coordinates you have used are to advanced :) |

calculate the volume of a zone I tried, but i have some problems doing so. I know that $$x^2+y^2<z<2ax+2by$$, therefore $$\int form (2ax+2by) to (x^2+y^2) dz=2ax+2by-x^2-y^2$$ which is a circle with the area of $$\pi (a^2+b^2)$$. now, y form $$b-\sqrt(b^2+2 a x-x^2)$$ to $$b+\sqrt(b^2+2 a x-x^2)$$ and x from $$\sqrt(a^2+b^2)-a$$ to $$\sqrt(a^2+b^2)+a$$. However, I don't know how to calculate the intergral.. |

Vectors / Linearly independent question i'm sorry guys. it is cross product. and i meant to prove that they ARE dependent |

Vectors question Thanks again. Last thing: if ||u||>1 and $||x_1||>1$, would $||x_n||->\infty$? |
