Question

$| \frac{x2}{y2} + \frac{y2}{z2} | | \frac{y2}{z2} + \frac{z2}{x2} | | \frac{z2}{x2} + \frac{x2}{y2} |$
​

Answer 1

Step-by-step explanation:

Differentiating with respect to t

2xdxdt+2ydydt+2zdzdt=02xdxdt+2ydydt+2zdzdt=0

then put x = 2, y = 2,z = 1 ,

dxdt=5,dydt=4dxdt=5,dydt=4

in above equation to get the answer of

dzdt
