The word Calculus originated from Latin, meaning "Little Pebble". In the ancient times, pebbles were used to work out sums, hence the adoption of the word.

Who invented Calculus?

The share of the credits goes to Sir Issac Newton (British) , Gottfried Wilhelm Leibniz (German), and Joseph Louis Lagrange (Italian).

Gradient

As learnt in Coordinate Geometry, gradient of a straight line is defined as rise/run.
, where m reps the gradient. What about the gradient of a curve?

In a curve, the gradient is always changing. It can go from positive, to negative and even become zero at some point. The point at which m = 0 is called the stationary point.

To find the gradient of a particular point on a curve, we could draw a tangent at that point and calculate its gradient (which could lead to an inaccurate answer), or we could use thegradient function.
