Question

Which strips are considered for the area bounded by \[y=f(x)\], the \[x\]-axis, and the ordinates \[x=a\] and \[x=b\]?

विकल्प

• Horizontal strips

• Strips of length \[x\] and width \[dy\]

• Strips bounded by the \[y\]-axis

• Extremely thin vertical strips

Answer 1

The region between the ordinates \[x=a\] and \[x=b\] is divided into a very large number of extremely thin vertical strips. Each strip has width \[dx\] and height \[y=f(x)\].
