x+2/根号下x+1的积分
x+2/根号下x+1的积分

x+2/根号下x+1的积分
∫(x+2)dx/√(x+1)
=∫(x+1+1)dx/√(x+1)
=∫√(x+1)dx+∫dx/√(x+1)
=(2/3)(x+1)^(3/2)+2√(x+1)+C

不定积分 2/3(x+1)^(3/2)+根号下x+1+常数C

∫[(x+2)/√(X+1)]dx
=∫[√(x+1)+1/√(x+1)]dx
=∫[(x+1)^(½)+(x+1)^(-½)]d(x+1)
=(2/3)(x+1)^(3/2)+2(x+1)^(½)+C从∫[(x+2)/√(X+1)]dx到
=∫[√(x+1)+1/√(x+1)]dx尤其是∫√(x+1) 怎么来的x+2=(x+1)+1...

全部展开

∫[(x+2)/√(X+1)]dx
=∫[√(x+1)+1/√(x+1)]dx
=∫[(x+1)^(½)+(x+1)^(-½)]d(x+1)
=(2/3)(x+1)^(3/2)+2(x+1)^(½)+C
