Calculus is a branch of mathematics that ... To find the slope at any point along the curve, we instead find the slope of the tangent line. The results of six points are plotted below: This ...

Note that the curve is steepest at around day 80; that is, around March 21. It's similarly steep, with negative slope, around day 250 (September 21). And it's flat at about day 170 (June 21 ...

Calculus is a powerful mathematical tool ... On the left side of this V-shaped curve, tangent lines slope downward. On the right side, they slope upward. At the bottom vertex, the slope abruptly ...

Calculus is a powerful mathematical tool ... Consider the “absolute value” function, which looks like this: On the left side of this V-shaped curve, tangent lines slope downward. On the right side, ...

This was Newton's insight when he invented calculus. Say, for instance, you've got a curve and you're trying to find the slope of the curve below at a specific point. This is the same as trying to ...
