Let me explain this by way of an analogy Which, as i understand it goes as follows: Suppose i teach you all the rules for adding and multiplying rational numbers
How to fix the differential oil leaks? - YouTube
Then you ask me but what are the rational numbers? the answer is
They are anything that obeys those rules
Now in order for that to make sense, we have to know that there's at least. See this answer in quora What is the difference between derivative and differential? In simple words, the rate of change of function is called as a derivative and differential is the actual change of function
We can also define a derivative in terms of differentials as the ratio of differentials of function by the differential of a variable. 69 can someone please informally (but intuitively) explain what differential form mean I am a bit confused about differentials, and this is probably partly due to what i find to be a rather confusing teaching approach (i know there are a bunch of similar questions around, but none o.
These are my answers to the questions, however, my teacher's answers are not the same as mine
What bothers me is this definition is completely circular I mean we are defining differential by differential itself Can we define differential more precisely and rigorously Is it possible to define differential simply as the limit of a difference as the difference approaches zero?
$$\mathrm {d}x= \lim_ {\delta x \to 0}\delta x$$ thank you in advance. A differential algebraic system of equations is a system of equations where some equations are algebraic equations and some are differential equations The equations need not be polynomial. 2 one could define a linear differential equation as one in which linear combinations of its solutions are also solutions.
Is the above definition of the second differential used today in mathematics
This is the question for which i will accept an answer Can the above definition be brought into consonance with the definition of the differential of a differential form
