(2/2)e grateful if you could help us.英译汉 grateful 一道基础的微积分题：If y''=2y' and if y=y'=e when x=0,then when x=1,y=?If y''=2y' and if y=y'=e when x=0,then when x=1,y=?（如果y''=2y' ,并且当x=0时y=y'=e ,那么当x=1时y等于多少?）A.( e^2 + 1 ) *e / 2B.eC.e^3 / 2D.e / 2E.(e^3 We would be grateful if you could help us.翻译 i will be grateful if为什么要有be y=(e^x-e^-x)/2 if y is an integer ,then the least possible value of /23-5y/ isA (1) B(2) C(3) D(4) E(5)请说为什么? #includemain(){int x=1,y=2,z=3;if(x>y)if(y int x=1,y=2,z=3if (x>y)if(y if(x) y+=2是什么意思 If you can help me,i will be grateful.If you could help me,i would be grateful.这两句话涵义区别 (2X - Y +E)(2X +Y -E) xy^2-e^x+e^y=1 求y' y'-2y=(e^x)-x ∫[(-y^2)*e(-y^3)]dy if(x!=y) return((x+y)/2)啥意思?
