#int x^2 arcsin(x)dx = # ? Calculus Introduction to Integration Basic Properties of Definite Integrals 1 Answer Cesareo R. Dec 28, 2016 #1/3x^3arcsin(x)+1/9x^2sqrt(1-x^2)+2/9sqrt(1-x^2)+C# Explanation: #d/(dx)(x^3 arcsin(x))=3x^2arcsin(x)+x^3/sqrt(1-x^2)# then #int x^2 arcsin(x)dx = 1/3x^3 arcsin(x)-1/3int x^3/sqrt(1-x^2)dx# now #d/(dx)(x^2sqrt(1-x^2))=2 x sqrt[1 - x^2]-x^3/sqrt[1 - x^2]# so #int x^3/sqrt(1-x^2)dx=int 2 x sqrt[1 - x^2]dx-x^2sqrt(1-x^2)# and #int 2 x sqrt[1 - x^2]dx=-2/3 (1 - x^2)^(3/2)# putting all together we have #int x^2 arcsin(x)dx=1/3x^3arcsin(x)+1/9x^2sqrt(1-x^2)+2/9sqrt(1-x^2)+C# Answer link Related questions What are five basic properties of definite integrals?
