Derivative of 2sinxcosx
WebNov 7, 2016 · Using, sin(2x) = 2sinxcosx we can write ∫(xsinxcosx)dx = ∫ 1 2 xsin(2x)dx = 1 2∫xsin(2x)dx So for the integrand xsin(2x), hopefully you can see that x simplifies when differentiated and sin (2x) changes to Acos(2x). Let {u = x =⇒ du dx = 1 dv dx = sin(2x) =⇒ v = − 1 2cos(2x) Then plugging into the IBP formula givs us: WebDerivative of sin 2x, Derivative of cos 2x, Derivative of 2sinxcosx, and Derivative of cos^2x - sin^2x#Derivative #Calculus #Differentiation
