Question

tangent at a point of a curve gives
a)integral
b)derivative
c)limit
d)incerment

Answer 1

point of a curve is derivative

Answer 2

At a given point on a curve, the gradient of the curve is equal to the gradient of the tangent to the curve.
The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.
