`intsqrt(1+cos x )dx` is equal toA. `2sqrt2 cos.(x)/(2)+C`B. `2sqrt2 s

1.	`intsqrt(1+cos x )dx` is equal toA. `2sqrt2 cos.(x)/(2)+C`B. `2sqrt2 sin.(x)/(2)+C`C. `sqrt2 cos .(x)/(2)+C`D. `sqrt2sin.(x)/(2)+C`
Answer» Correct Answer - B `intsqrt(1+cosx)dx=intsqrt(2cos^(2).(x)/(2))dx` `=sqrt2intcos.(x)/(2)dx=2sqrt2.sin.(x)/(2)+C`
