Misc 3 Find the area bounded by the curve π¦=sinβ‘π₯ between π₯=0 and π₯=2π Area Required = Area OAB + Area BCD Area OAB = β«_0^πβγπ¦ ππ₯γ π¦βsinβ‘π₯ = β«_π^π βγπ¬π’π§β‘π π πγ = [βcosβ‘π₯ ]_β( @0)^π =β [cosβ‘πβcosβ‘0 ] =β[β1β1] =β[β2] = 2 Area BCD = β«_π^2πβγπ¦ ππ₯γ = β«_π ^ππ βγπππβ‘π π πγ = [βcosβ‘π₯ ]_β( @ @π)^2π =β [cosβ‘2πβcosβ‘π ] =β[1β(β1)] = β 2 Since area cannot be negative, Area BCD = 2 Hence, Area Required = Area OAB + Area BCD = 2+2 = π square units
