What is the probability of the box? Definitely, but I think it's also useful to do some easy problems with more complicated machinery, just to see how things work. |

Proof of Correlation Theorem Jennifer, welcome to math.se! I would suggest you add what you have done so far so your question, or make it clear what in the linked image is your own work. Also, note that math.se happily interprets $\LaTeX$, so if you have the source for that image you can just paste it into your question. |

How is $e^x$ read aloud? Perhaps not in the first explanation of an equation, but if you have to say it many times, that's what I default to. Particularly reading/taking about anything in continuous time finance, $e^{-rT}$ quickly becomes 'ee minus arr tee' for me. |

calculus of variations question @Rut welcome to math.se! Posts of this nature should usually be comments on the main question rather than answers. The latter are generally reserved for complete solutions to the problem at hand. |

Sum of Infinite Surds I'm not quite sure I understand precisely the value you're computing. Is it: $$\sqrt{10+\sqrt{100+\sqrt{1000+\cdots}}}$$ |

Trig to determine distance: boat on course parallel to shore. Draw it out first. Can you see how the boat's path in the problem forms a triangle? |

Cubic equation - finding coefficients I agree with the above comments that this is not at all the appropriate form for this question. That said, if I interpret your variable names correctly, you fit the parabola with equation $$ax^2+bx+c$$ through three points, $p_1=(x_1,y_1), p_2=(x_2,y_2), p_3=(x_3,y_3)$ and propose to do so with the equations $$ a=\frac{((y_2-y_1)(x_1-x_3))+((y_3-y_1)(x_2-x_2))}{(x_1-x_3)(x_2^2-x_1^2)+(x_2-x_1)(x_3^2-x_1^2)}$$ $$ b= \frac{(y_2-y_1)-a(x_2^2-x_1^2)}{x_2-x_1} $$ $$c = y_1-ax_1^2 - bx_1 $$ and are asking for a similar equation to fit a cubic through three (or four?) points. |

Building Intuition for Matrix Multiplication @Alex I know what matrix multiplication means, I'm asking for ways to perform it quickly, or at least 'know' categorical/broad stroke information about the products at a glance. |
