But it seems to me that a=−10,b=2,ab=−20a=−10,b=2,ab=−20 works as well, but is excluded by their inequality.I wasn't confident in their method of multiplying inequalities, but this answer suggests that it is indeed valid....
A major feature of differential calculus is the use of graphs. Any problem in which the answer is defined as one point on a graph is where differential calculus is involved. It usually identifies the steepness of a curve, commonly known as the slope. In real world applications, the steepness...
The derivative, 1/(x-2)+ 1/(x- 6), is positive for all x> 6 which is the domain of the function. The derivative is always positive, never negative on the domain of the function. (Why are so many people posting derivative, integral, and even differential equation...
