Dick said:Now I don't understand what your picture is trying to tell me either. The proof of the limit in your first post is just fine.
HallsofIvy said:You have now posted 3 different pictures that appear to involve three different problems. As Dick told you before, the first is correct. This third one is also correct- except for spelling: since you get two different limits by approaching (0,0) along two different paths, the limit does not exist.
My answer of the first question :
is correct or a mistake?
I'm not sure what the second picture was supposed to represent. But one thing you should be careful about: The line y= 2x, for example, in R2, is not in the complex plane.
Dick said:lim(z->0) is not the same as lim(x->0) or lim(y->0). It's lim(x->0 AND y->0).
m_s_a said:Look into the proof of Coshi theory - Riman
f'(z)=f'(x)=f'(y)
no f'(z)=f'(x)+f'(y)
The purpose of studying compound functions is to understand how different functions can be combined to create more complex mathematical relationships. This knowledge can be applied in various fields such as physics, engineering, economics, and computer science.
Number paths in compound functions refer to the sequence of numbers that are used as inputs and outputs in a compound function. These numbers follow a specific pattern and can be visualized as a path on a number line.
Remembering number paths in compound functions is important because it allows us to understand how the inputs and outputs are related and how the function behaves. This knowledge can help us make predictions and solve problems involving compound functions.
Some common mistakes when working with compound functions include not following the correct order of operations, misinterpreting the number paths, and using incorrect inputs. It is important to carefully follow the rules and understand the concept behind the function to avoid these mistakes.
To improve your understanding of compound functions and number paths, you can practice solving problems, work with different types of functions, and create visual representations such as graphs or number lines. It is also helpful to seek guidance from a teacher or tutor if you are struggling with the concept.
