Question
Let f (x) be a non-negative continuous function such that the area bounded by the curve y = f(x), x-axis and the ordinates x =
and x = β >
is
. Then f
is
and x = β >
is
. Then f
is Options
A.

B.

C.

D.

Solution
Given that
f(x)dx = β sin β +
cos β + √2β
Differentiating w. r. t β
f(β) = β cosβ + sinβ -
sinβ + √2

f(x)dx = β sin β +
cos β + √2β Differentiating w. r. t β
f(β) = β cosβ + sinβ -
sinβ + √2
