# Doubt from area

Is it B?

Its C

Accha.. its a ques from my friend so i don't know he said it was C ... please tell your approach .. @Bharat_2020

idk whether its exactly right ,but.....

Take out intervals where sinx+cosx are negative and positive

Then use m(b-a)< ∫f(x)dx<M(b-a) m and M are the least and max value of f(x) in the interval [a,b]

U should get an approx ans .

Take this ans with a pinch of salt. I may be wrong
