Given that z is equal to f of xxx0 .y is equal to x square plus yk and x is equal to that is 5, y is equal 3, del x is equal to 0 .03 and del y is equal to 0 .0.
00:39
We need to find first we need to estimate estimate value del z.
00:55
Second b part we can find actual value del j as we can see that for first part the estimate value can be evaluated as we need to find first d z is equal to del f over del x multiplied d x del y multiply d x del y multiply t y multiply d y so it can retain as del z is equal to f of x dal x, f of y, deli.
01:44
As after solving, make it 10 z is equal to derivative of a with straight x, that is 2 x twice of x, del x, derivative of f with respect to y, that is 3 y square, deli.
01:59
Now substitute all the value.
02:04
Twice of the value of x is 5, value of del x that is 0 .03, plus 3, value of y, 0 .02.
02:15
Full square value of that is 3 and value of y that is 3 full square value of del y that is 0 .0 after solving we get this is 0 .3 plus this is 0 .54 so after adding this we get 0 .80...
