What is the formula used to find the area surrounded by the curves in the following diagram?
(a) \(\int_c^d y \,dx\)
(b) \(\int_c^d -y \,dx\)
(c) \(\int_c^d x \,dy\)
(d) \(\int_c^d -x \,dy\)
I have been asked this question in examination.
Origin of the question is Quadrature in division Integral Calculus of Engineering Mathematics
