This is part of the HSC Mathematics Advanced course under the topic of Integral Calculus: Areas and the definite integral
In this post, we learn that ‘the area under a curve’ refers to the area between a function and the x-axis, bounded by two values of the independent variable and interpret the area under a curve in a variety of contexts to solve problems.
