To calculate the area between a curve and the \(x\)-axis we must evaluate using definite integrals. First, we need to find out where the curve cuts the \(x\)-axis. Remember, a curve cuts the ...

Revise how to find the area above and below the x axis and the area between two curves by integrating, then evaluating from the limits of integration. Higher Maths - Applying integral calculus.
