if A denotes the area bounded by f(x)=mod (sinx+cosx whole divided by x),x axis ,x=Π and x=3Π the A what r the max and min value of A

3 years ago

Share

Ans:
Using the inequality
$m(b-a)\leq \int_{a}^{b}f(x)dx\leq M(b-a)$
$a = \pi , b = 3\pi$
$m\leq f(x)\leq M$
Max. value of A
$2\pi M$
Min. value of A
$2\pi m$
You can easily find the m & M from f(x) (I am not finding b/c f(x) is not clear)

Calcilate the area bounded between the curves y = x and y = lnx from 0 and 1.

Ans: Hello Student, Please find answer to your question below y = x y = lnx Area b/w curves ‘A’
