解答

展开

d y + (y cot (g) x - e^{c o s (x)}) d x

d y + y x cot (g) d x - e^{c o s (x)} d x

求解步骤

d y + (y cot (g) x - e^{c o s (x)}) d x

= d y + (y x cot (g) - e^{c o s (x)}) d x

乘开

d x (y cot (g) x - e^{c o s (x)}) : y x cot (g) d x - e^{c o s (x)} d x

= d y + y x cot (g) d x - e^{c o s (x)} d x

e x p an d (a e^{x} - b e^{- x})^{2}

e x p an d - 3 x (c_{1} (2 x ln (x) + x))

e x p an d \frac{s ^{3} + 1}{s ( s - 1 ) ^{3}}

e x p an d e^{((- 3 + 5 \cdot I) \cdot x)}

e x p an d \frac{2 ( ab + a c + b c )}{ab c}
