To solve area between two curves problems in NCERT Class 12 Maths, identify the two functions: y = f(x) and y = g(x), where f(x) >= g(x) in the interval [a, b]. The area between the curves from x = a to x = b is:

$\text { Area }=\int_a^b[f(x)-g(x)] d x$

This gives the vertical distance between the curves integrated over the interval. Sketching the curves helps visualize the region. Always check which function is on top within the limits.
