Detailed Solution
Download Solution PDFభావన:
x = a & x = b మధ్య y = f(x) వక్రరేఖ క్రింద ఉన్న వ్యాసార్థం (A) ద్వారా ఇవ్వబడింది,
A = \(\rm \displaystyle\int_a^b f(x) \ dx\)
లెక్కింపు:
ఇక్కడ, వక్రరేఖ x = f(y) మరియు రేఖలు y = a మరియు y = b
∴వ్యాసార్థం = \(\rm \int _a^bf(y)dy \cdots (\text{function is f(y)})\)
= \(\rm \displaystyle\int_a^b x \ dy\)
(∵ f(y) = x)
కాబట్టి, ఎంపిక (3) సరైనది.
