How Do You Find The Integral X Sin X 2 Dx Socratic

How Do You Find The Integral X Sin X 2 Dx Socratic Explanation: use integration by parts, which takes the form: ∫udv = uv − ∫vdu. for ∫udv = ∫x2sin(x)dx, we let: u = x2 ⇒ du dx = 2x ⇒ du = 2xdx. dv = sin(x)dx ⇒ ∫dv = ∫sin(x)dx ⇒ v = − cos(x) thus, substituting these into the integration by parts formula, we see that: ∫x2sin(x)dx = −x2cos(x) − ∫(− 2xcos(x))dx. Show the steps below: substitute u = √2 ⋅ x √π. dx = √π √2 ⋅ du. ∫sin(x2) ⋅ dx. = √π √2 ∫sin(π ⋅ u2 2) ⋅ du. these is special integral fresnel integral. = s(u) plug in solved integrals: √π √2 ∫sin(π ⋅ u2 2) ⋅ du = √π ⋅ s(u) √2.

How Do You Integrate Sinx 2 Dx Socratic If we solve for sin(a), we have the half angle formula, but is we stop at solving for sin2(a), the we have the power reduction formula for sinx. sin2x = 1 2(1 − cos(2x)) ∫sin2xdx = 1 2∫(1 − cos(2x))dx. = 1 2 [x − 1 2sin(2x)] c. rewrite the answer to taste. i like 1 2 (x − sinxcosx) c. additional note. using the cosine double.
