In more general considerations, h is often used in place of Delta-x.Or Delta-y is used in place of This leads to three commonly used ways of expressing the definition of the derivative: The definition of continuity says nothing about the magnitudes of $\epsilon$ and $\delta$, except that they are strictly positive. Rather, the techniques of the following section are employed. Example: Prove the statement using the epsilon delta definition of limit of a function that the function f, defined by f\left ( x \right ) = \sin \left ( \frac{1}{x} \right ) , when x \neq 0 and f(0) = 0 , does not approach 0 as x \rightarrow 0 . Can mean, variation of a variable or function. Delta, is just a greek letter very used in Math. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. 2 : something shaped like a capital Greek delta especially, geology : the alluvial deposit at the mouth of a … It only takes a minute to sign up. Which you'll find to be very similar to the definition of a derivative in calculus: [itex]\frac{\delta y}{\delta x}[/itex] which basically means (difference in y)/(difference in x) Capital delta is looking for a specific answer (most times) while lower case is looking for another equation (most times). Because the letters simply represent angles, knowledge of the Greek alphabet and its order isn't necessary to understand their significance in this context. Mathematics. Upper-case delta (Δ) often means "change" or "the change in" in mathematics. He also worked in an online writing center for college students.
