Madhava of Sangamagrama is widely regarded as the father of Indian Calculus due to his significant contributions to the field, including the development of the concept of the derivative and the mean value theorem.

Madhava of Sangamagrama developed a series expansion for the sine function, known as the Madhava Series, which is considered a precursor to the Taylor Series.

Brahmagupta was the first mathematician to explicitly define and use the concept of the zero as a number in his mathematical calculations.

The Fundamental Theorem of Calculus is a central theorem in calculus that establishes a connection between differentiation and integration, allowing for the calculation of areas under curves.

Bhaskara II developed a method for solving indeterminate equations, which are equations that have multiple solutions.

The Extreme Value Theorem states that if a function is continuous on a closed interval, then it attains both a maximum and a minimum value on that interval.

Madhava of Sangamagrama developed the concept of the derivative, which is a fundamental concept in calculus.

Darboux's Theorem states that if a function is differentiable at a point, then it is continuous at that point.

Brahmagupta developed a method for solving quadratic equations.

Rolle's Theorem 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.

Bhaskara II developed a method for solving cubic equations.

Darboux's Theorem states that if a function is differentiable at a point, then it has a unique tangent line at that point.

Nilakantha Somayaji developed a method for solving quartic equations.

The Mean Value Theorem 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 equal to the average rate of change of the function on the closed interval.
