But the problem here is I wanna come up with the k, I'd like a resolve for a k. It would not be nice if this turned out to be 0. if this turned out to be one, or if this turned out to be negative one But now I see, given the assumptions right here this could be ANY this could be absolutely any k I cannot determine what k this should be This could be a hundred thousand, this could be 75, it could be anything true for any k I cannot determine what k this should be and that's why when you get a little bit more nuance in early math people will say, well 0 divided by 0, well we don't know what that's gonna be there's no consistent answer there so we're just going to call it undefined there's no good answer that seems better than any other answer but now we see a little bit nuance here one divided by zero you just couldn't define it it led to direct contradictions zero divided by zero it could be anything you can't determine it and so that's why, when you do higher level math and you'll often hear this when you take a calculus course we see that zero divided by zero is indeterminate. Six less than a number equals two. and then each took the same number of cookies. A definition is just a description of our mathematical object. Now divide the total by the number of data points. Let us assume the number to be a variable. The graph consists of 2 lines. Because all the numbers in the data set have a clone, and the string of cloned numbers stretches to Infinity, there is infinite modes. Using these ideas we were able to build up a foundation for calculus which eventually lead to the physics that put man on the moon. conversely, if OP doesn't "'accept complex conjugation," then he's probably asking if there is a holomorphic formula for them, and then the answer is no. It's used like this: x, x > 0. In truth, you are nudging up against one of the most powerful and changing ideas in mathematics. Let the number be x. The difference is subtle. Dimitri has three bananas above his name. Set Symbols - Math is Fun And once again, I am not willing to give up the idea that if I start with a number x, I divide it by something over which division is defined, and then I multiply by that something, I should get my original x again. Basic terms in algebra are numbers, constants, equations, variables, linear equations, quadratic equations, etc. The limit exists because the same y-value is approached from both sides. As formulas are entirely constituted with symbols of various . This brings us to a biconditional statement, which is also known as an "if and only if" statement. Also, just take a deep breath. This has to be equal to that. This helps to condense many decimal places or multiple orders of magnitude into a smaller mathematical expression that is easier to read. can you please like my other one because if you don't my mom will kill me.

My guess is E stand for Exponential and -5 is the power it is raised to. In other words, E (or e) is a short form for scientific notation. But what about when x DOES equal zero. You can usually pick out the use cases of a number e compared to the letter E (as used for scientific notation) by context, or you can look for the E to be sandwiched between two other numbers. The graph of function f has arrows pointing along the line, pointing up to the right and down to the left, respectively, pointing to point (3, 5). It is used to evaluate expressions involving complex numbers and it describes compound interest in many situations. For the last question, how is there a limit for x-->6? For example, suppose we wanted to be, This is endless. When a limit doesn't approach the same value from both sides, we say that the limit doesn't exist. Can a limit ever be "undefined" or is it strictly described as "none existent"? We can see how, when we approach the point where. However, this statements converse If a number is divisible by 2, then it is divisible by 4 is false. I loved Calculus 1. Learn more about Stack Overflow the company, and our products.
