This video shows the process for solving the problem presented in IGCSE A June 2018 paper 2H Q15, which involves finding the lower bound of the difference between two values. Students will understand the concept of lower bounds and their...

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 2HR Q19, which involves bounds. By using algebraic manipulation and rounding to the correct number of significant figures, we will work through the...

👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

This video provides a tutorial on how to solve limits of accuracy problems in math. The lecturer begins by recapping the concept of error intervals and how they consist of upper and lower bounds. The lecture then proceeds to demonstrate...
