Learn about differentiability. Understand how to tell if a function is differentiable and when it isn't and see a comparison of differentiable vs. continuous. Related to this Question How to prove figure eight i
Types of Functions: How To Know if It’s a Function Thevertical line testis a simple way to figure out if you have a function. You could also use to “many to one” rule: Is a function: “many to one“. This is saying if you have multiple x-values that map to one y-value —...
Answer to: Explain how to determine if a function is invertible. By signing up, you'll get thousands of step-by-step solutions to your homework...
where multiplication needn't be commutative). In Lean, we like to make every lemma as general as possible. A part of the reason is that we can make reasoning "by lemma XYZ" but not reasoning "by the
How to Calculate the Derivative of a Function The first way of calculating the derivative of a function is by simply calculating the limit. If it exists, then you have the derivative, or else you know the function is not differentiable. ...
The absolute value parent function is written as: f(x) = │x│ where: f(x) = x if x > 0 0 if x = 0 -x if x < 0 As the definition has three pieces, this is also a type ofpiecewise function.It’s only true that the absolute value function will hit (0,0) for this very...
Let g(x) and h(y) be differentiable functions, and let f(x, y) = h(y)i+ g(x)j. Can f have a potential F(x, y)? If so, find it. You may assume that F would be smooth. (Hint: Consider the mixed partial derivatives of F.) How to answer this question? Wh...

If a fickle indicator is relevant for the research questions, it should be paired with other robust indicators, allowing the evaluation to spot (and possibly penalise) systemic perversion (Moed & Halevi,2015) to correct them. All these risks reaffirms the pragmatic convenience of a systemic appr...
It appears only to accept integer input. (It uses factorial, for example.) So it is NOT differentiable. fmincon will NOT work, nor will any tool that assumes smoothness in any form.What is the objective function (the thing that you are trying to maximize)...
