∫sin(x^2)dx进行求导是=sin(x^2)还是=2xsin(x^2)?

∫sin(x^2)dx进行求导是=sin(x^2)还是=2xsin(x^2)? 求不定积分 ∫(sin^5x sin^2x)dx抱歉是∫(sin^5x+sin^2x)dx ∫sin(6x)sin(2x)dx=? sin^2(x)求导 ∫(2/sin^2x)dx= 求导：∫sin(x*x)dx及∫e^(-x*x)dx 设sin（xy）-x^2y=0,求dy／dx,求导什么的都要疯了! y=[sin^2(x)]*[sin^2(x)]求导 sin(x^2)/sin^2x 求导 y =sin(2x-1)求导! y=e^[(sin^2)x]求导! ∫sin^2x/(1+sin^2x )dx求解, ∫sin(5x)sin(7x)dx= sin^2x反求导 sin(πx/2)求导 ∫x/sin^2(x) dx ∫sin(x) cos^2(x)dx 被积函数含变限函数变量的积分求导I（y）=∫sin(xy)/x dx,上限y^2,下限y求I'（y)[2sin(y^3)-2sin(y^2)]/y
