So... I was feeling kind of hip so I started simplifying the 1/8 - cos(4x) /8 into terms with only x and I ended up with just sin^2(x) cos^2(x).. Now that's pretty interesting right cause it's the same as the integrand plus a constant. Anyone tried this?####[['sin^2(x) cos^2(x)', 'Mathematical_Related_Concept', 'POS'], ['NULL', 'Mathematical_Related_Concept', 'POS']]
