What Is The Formula For (X+Y+Z) ^3?

     
Applying the AM-GM is the right strategy, but you need to bởi vì it a bit differently. X^2+4xy+4y^2+4z^2 = x^2+2xy+2xy+4y^2+2z^2+2z^2 ge 6sqrt<6>x^2 cdot 2xy cdot 2xy cdot 4y^2 cdot 2z^2 cdot 2z^2 ...

fMy; Solution:: We Can write xcdot ycdot z= 3000 = 2^3cdot 3^1cdot 5^3 Now let x=2^x_1cdot 3^y_1cdot 5^z_1 & 2^x_2cdot 3^y_2cdot 5^z_2 và 2^x_3cdot 3^y_3cdot 5^z_3 ...
This is intended as a complement to Alex Bartel's answer. (1) Consider the 2d case given by x = x(t), y = y(t). Here is a graph of a parametrized function with (x(t_0),y(t_0)) (in red) và (x(t_0 + delta), y(t_0 + delta)) ...

In general, such a line will be parametrized by x = az + 2, y = bz + 5 unless the line lies on the plane z = 0, which is easy lớn see not to lớn be the case. In a more general case, the linear ...
the gradient is indeed the solution. Take a curve, gamma that lies in S. Then Fcirc gamma is zero everywhere. So its derivative is zero. But its derivative is just abla F(gamma(s)). gamma'(s) ...

What you actually want here is the point-line distance formula for three dimensions . However, the cylinder equation you did get is correct. Using formula 10 in the links I gave, we have r^2=frac^21^2+1^2+1^2=frac(z-y)^2+(x-z)^2+(y-x)^21^2+1^2+1^2 ...
