I get the Answer Zero
Question is = > f(x)= sin(x)+2cos(y)
Need to know that by putting the different value of x and y in the same code
>> syms x y
>> f=inline('sin(x)+2*cos(y)','x',' y')
f =
Inline function:
f(x, y) = sin(x)+2*cos(y)
>> derivative=inline(diff(f(x,y),x,y),'x','y')
derivative =
Inline function:
derivative(x,y) = 0.0
>> derivative(2,5)
