Aryabhata is often referred to as the father of Indian mathematics due to his significant contributions to various mathematical fields, including calculus.

Bhaskara II, also known as Bhaskaracharya, is credited with developing the concept of the derivative in the 12th century.

Indian mathematicians developed the Trapezoidal Rule, a method for approximating the area of a curved surface by dividing it into trapezoids.

Brahmagupta made significant contributions to the development of the concept of the integral, particularly in the context of finding the area of irregular figures.

Indian mathematicians developed the Taylor Series expansion method, which allows for approximating the value of a function using its derivatives.

Brahmagupta made significant contributions to the theory of interpolation, developing methods for approximating the value of a function at intermediate points.

Bhaskara II is credited with developing the concept of the mean value theorem, which states that there exists a point on the graph of a function where the tangent line is parallel to the secant line.

Indian mathematicians developed Euler's Method, a numerical method for approximating the solution of a differential equation.

Bhaskara II made significant contributions to the theory of limits, developing methods for determining the limit of a sequence or a function.

Bhaskara II is credited with developing the concept of the Rolle's theorem, which states that if a function is continuous on a closed interval and differentiable on the open interval, then there exists a point in the open interval where the derivative is zero.
