Solving an equation with $x$ as powers I just solve it before you posted your hint. Thanks anyway) |

Solving Compound Interest using Ordinary Differential Equation the equation $y'=ry$ states that the change in y (which is $y'$) equals interest rate (which is r) multiplied by y. But $r*y$ is the amount by which y changes. You see that? Ex.g. Lets say interest rate is 10%, r=0.1, and our investment is 50 bucks, y=50. So when compounded the change of our investments, $y'$, is going to equal to r*y=5. So, our return will be 5 bucks. To check 50*1.1=55. However, notice that I am using constants for y whereas in your book they refer to fucntions of time $y(t)$. This ODE is mere reasoning. Change in deposits,y', equals the interest rate share of your deposits |

Different solutions of $x+y+z=10$ where $x$, $y$, $z$ are positive integers. Is it 9 choose 2? |

To determine whether the integral $\int_0^{\infty} \frac{\sin{(ax+b)}}{x^p} \,\mathrm dx$ converges for $p>0$ Wolfram alpha says that this integral converges for any $p$. Ok I take it back. my edit was incorrect. But how would I show that the integral in question converges for p smaller than 1? I guess babydragon's explanations is the best we can get. |
