    Table calculation doesn't match actual drawing dimensions

    How come a calculation worked through trig tables doesn't exactly match the actual drawing dimensions? For example, a distance calculated by the tables should come out to 63.3200 mm but actually comes out to 64.4345 mm when drawn to 100 per cent size on CorelDraw. That's an error of about...

    Probability of drawing a match between two decks

    I'm now flipping through some old exam questions and found this: Q. Design an experiment of having two people drawing N times from two identical decks consist of N cards. Define the event "match" if both people draw the same card during the same draw, for example, both people drawing the...

    Calculating resize amount needed to match of image sizes of difference FOVs (AOVs).

    Hi, I am trying to work out the scaling factor required to match up the size of objects in 2 photos, taken from the same position, with different (known) Field/Angle of views. (You could also use it to find out the FOV of one image if you know the FOV of another and work out the scaling factor...

    Does the function u match the differential equation

    Problem statement: If u=\frac{1}{r} where r=\sqrt{(x-a)^2+(y-b)^2+(z-c)^2}, for r\ne0 prove that \bigtriangleup u \equiv \frac{\partial^2 u}{\partial x^2}+\frac{\partial^2 u}{\partial y^2}+\frac{\partial^2 u}{\partial z^2}=0 This is my approach: \frac{\partial u}{\partial x}=\frac{\partial...

    Formula to match a pattern

    Hello, I'm working on a formula used currently in a game and I'm having issues. There are two such formulas in this game that I'm working on, and I've already figured out one - I'll post it as an example that may/may not help in figuring out the formula I'm working on now. Available operations...

    Differentiate Solution and Match Up with Equation

    For C, can someone show me step-by-step how to isolate the function y and/or its derivatives? I said "and/or" just in case, I cannot isolate the function y itself but can for its derivatives so that I can say that the equation C is the general solution of one the numbers. Any help would be...

    Metric spaces that don't match

    Consider X(n) the set of every ordered n-tuples of zeroes and ones. Prove that X(n) is a metric space with the metric d(x,y) is the number of entries where x,y don't match. I have no idea what to do here... I know what a metric space verifies, but I don't get how to define d(x,y) explicitly.

    Need help finding best match between two unordered sets

    I have two sets of data, each with approximately 300,000 rows, and 20 columns. My goal is to find the row in set 'b' that would require the fewest changes for it to match the row in set 'a'. The order of the 20 columns is important. The data in each column can be any one of about 300...

    Adjusting Probabilities To Match Empirical CDF

    I have two data sets and can calculate the empirical CDF accordingly for each in Matlab. However, the ecdf's may or may not be similar to each other. My end goal is to force one data set to match the ecdf of the other. However, each ecdf does not necessarily match some known distribution...
