got a simple problem.(adsbygoogle = window.adsbygoogle || []).push({});

the question is find min value for f=x*y+(z^2) with constraints 2*x -y=8, and co-ordinates where it occurs.

so far what i did.

▽f=λ*▽g

F(x,y,z)=f(x,y)-λg(x,y,z)

F=(xy+z^2)-λ(2x-y-8)

y=2λ

x=λ

i got λ=-2

is this right? and is that the only λ value?

how do i even start to find equilibrium solutions & general solution to ((t/2)-2)*sin(y), we weren't taught or shown how to find it involving sin,cos, tan?

for general solution i should take it as separable to find the general solution? but how do i start? sin, cos, tan bah
