Evaluate the integral. π/2 sin2 x cos2 x dx 0

WebThis seems pretty simple to me but I can't get it. $$\int \sin^2 x \cos^2 x dx$$ $$\int (1-\cos^2 x) \cos^2 x dx$$ I know there is a rule in my book (with little explanation) that tells me when I had an odd and an even degree on two trig functions I should split the odd and convert it to an identity but this way seems easier, and I can't get an answer either way.

Question: Evaluate the integral. π/2 sin2(x) cos2(x) dx 0

WebMethod 1: Integral of Sin^2x Using Double Angle Formula of Cos. To find the integral of sin 2 x, we use the double angle formula of cos. One of the cos 2x formulas is cos 2x = 1 … WebMay 15, 2016 · Recall that through the Pythagorean Identity #sin^2(x)=1-cos^2(x)#. Thus, #sin^3(x)=sin(x)sin^2(x)=sin(x)(1-cos^2(x))#. Substituting this into the integral we see: #intsin^3(x)cos^5(x)dx=intsin(x)(1-cos^2(x))cos^5(x)dx# Distributing just the cosines, this becomes #=int(cos^5(x)-cos^7(x))sin(x)dx# Now use the substitution: #u=cos(x)" "=>" … cummings \\u0026 davis funeral home https://iaclean.com
