How to prove that a function exists?Function in Math:The function can exist or can't exist, that depends on if the function is function or a relation. So we have to test the function if it is not a relation, in order to guarantee its nature and type....
3. Things to knowThe SUMPRODUCT function is one of the most powerful functions in Excel and is one that I often use. I highly recommend learning how it works.The SUMPRODUCT function requires you to enter it as a regular formula, not an array formula. However, there are exceptions. If ...
How to find the limit of functions in calculus. Step by step examples, videos and short definitions in plain English. Calculus made clear!
Excel cannot determine the square root of a negative value, as was already established. The attempt will result in a#NUM!error. Make sure the input value is positive or zero to prevent this problem. If you forget to apply the parentheses: Use parentheses to ensure the proper sequence of op...
To find an inverse function in math, you must first have a function. It can be almost any set of operations for the independent variable x that yields a value for the dependent variable y. In general, to determine the inverse of a function of x, substitute y...
Example Problem 1: How to Determine that a Quantity Increasing Exponentially Eventually Exceeds a Quantity Increasing Quadratically by Constructing a Function Table Consider the following two functions, f(x)=2xg(x)=x2−x+3 Which...
Formula in cell C20: =COT(B18) Cell C20 returns the cotangent ratio which in this example is 1. Determine opposite side (a) if the adjacent side (b) is equal to 1 and the angle (A) is equal to π/4 radians? Cotangent A = b/a ...

In addition to this direct creation of arrays, both MATLAB and NumPy support a number of other methods to create arrays without explicitly specifying each element. The NumPy project maintains a detailed list of the equivalent functions between MATLAB and NumPy. Many functions operate identically ...
You can access these functions via the Function Library: Select cell D5. Go to Formulas > Math & Trig > LN / LOG / LOG10 (choose the desired function). Select the LOG function from the drop-down menu. In the Function Argument pop-up dialog box, select the appropriate cells for the ...
