Question

# Plz explain that what is delta of lowercase

Solution

## Often the upper case delta is used to represent a difference between two quantities. For example, the slope of a line is Δy/Δx = (y2-y1)/(x2-x1). The symbol can often be read as the word "change" as in, "change in y divided by change in x". The lower case delta is often used to represent the infinitesimal change much of calculus is based on.
