微积分问题四题
y = −x^7 +1/ x^3 −（5次方√x）
y = 5cos(4x^3− 1)tan(x)
y = sin√(x^2 − 7x^−1)
y =3e^x− 2x^3/3e^x + 2x^3

微积分问题四题y = −x^7 +1/ x^3 −（5次方√x）y = 5cos(4x^3− 1)tan(x)y = sin√(x^2 − 7x^−1)y =3e^x− 2x^3/3e^x + 2x^3

 y=-x^7+1/x^3-x^(1/5),    y'=-7x^6-3/x^4-(1/5)x^(-4/5).

y=5cos(4x^3-1)tanx,    y'=-60x^2sin(4x^3-1)tanx+5cos(4x^3-1)(secx)^2.

y=sin√[x^2 − 7x^(−1)],    y'={[x+7/(2x^2)]/√[x^2 − 7x^(−1)]}cos√[x^2 − 7x^(−1)].

y =3e^x− 2x^3/(3e^x) + 2x^3,    y'=3e^x-(2/3)(3x^2-x^3)/e^x+6x^2
