You can get at the error messages and source position of an error using the errorMessages, messageString, errorPos and sourceColumn functions from Text.Parsec.Error. Here is an example taken from this blog post. It demonstrates the use of <?> and using the above mentioned functions to customize error processing: import Text.ParserCombinators.Parsec...

In C, the ^ operator is not exponentiation. Instead, in C, we write ex as exp(x). Other than that, your equation is the same in C. I would put spaces around some of the operators, though: Eq = sqrt(exp(-(T - thr) / T)) + (1 - a) / 4; I...

The original question has been edited, this answer has been updated to reflect this. When trying to work with LaTeX formatting in matplotlib you must use raw strings, denoted by r"". The code given below will iterate over range(4) and plot using i'th mean and variance (as you originally have...

1: No difference. It is keep around to allow old S-code to continue to function. This is documented a "Note" in ?Math 2: Yes: But you already know it: `^`(x,y) #[1] 1024 In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function...

The code you provided will run as you explained sum it for i = 1 with all j = {1, 200} and i = 2 with again all j = {1, 200} and so on However, the mathematical equivalent is without the condition marked in red. The sigmas with the...

You need to cast your INT to a more precise format; in your case is should be DECIMAL (X,3). UPDATE Test SET Planned_Headcount = 175+(2.879546*(CAST([Date_Key] as DECIMAL(X,3))-25)) The "X" above should be a number that large enough to contain the results of your math. 12 would likely suffice, but you...

This is a math question, not a coding question. Use linear regression without the intercept term. public static LineSpec LinestConst(IList<double> yValues, IList<double> xValues) { var yAvg = yValues.Sum() / yValues.Count; var xAvg = xValues.Sum() / xValues.Count; double upperSum = 0; double lowerSum = 0; for (var i = 0; i...

-2(10^ -10)x^6 The above statement will never work. It will give you an unexpected identifier because of )x and 2 is not a function because of -2(.. -2 * math.pow(10, -10) * math.pow(x, 6) This will also won't work as its Math and not math as Javascript is case-sensitive....
