1/(sin^3x cos^5x)^(1/2）积分啊啊啊

求积分：∫sin^2 (x) /cos^3 (x) dx 化简（1)√3sin x+cos x (2）√2(sin x-cos x) （3）√2cos x-√6sin x (sin(x)*cos(x))^(1/3)',x,-pi,pi))求积分的matlab程序! 化简 1/2cos x-根号3/2sin x 根3sin x+cos x 化简[1-(sin^4x-sin^2cos^2x+cos^4x)/(sin^2)]+3sin^2x 高数积分∫1/（cos⁴x+sin⁴x）dx 化简2sin^2[(π/4)+x]+根号3（sin^x-cos^x）-1 积分练习题 ∫tan(x)dx 定积分在0到1/4π ∫(cos(x)ln(x)-sin(x)1/x)/ln^2 (x) (1-(sin^4x-sin^2xcos^2x+cos^4x)/sin^2x +3sin^2x 2cos x (sin x -cos x)+1 sin^2(x)cos^2(x)积分等于多少 积分(cos x)/(3+sin平方x)dx
