Nettetf (x)dx前面加上积分号∫就是微分的逆运算，即已知导函数f (x)，求原函数F (x)的运算，不定积分。如果是∫f (x)d (cosx)，那么证明原函数的变量不是x，而是cosx而已。求解时要保持f (x)中的x与d后面的x相一致。所以要把x换成cosx，并且保持等价：∫f (x)d (cosx) = ∫f (x)· (-sinx)dx。 44 评论分享举报麦秀丽礼爽 2024-02-05 · TA获得超过3万个赞关注 d—— … NettetFree Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step
