Webcalculates the partial derivative ∂ f / ∂ t. The result is ans = s*cos (s*t) To differentiate f with respect to the variable s , enter diff (f,s) which returns: ans = t*cos (s*t) If you do not specify a variable to differentiate with respect to, MATLAB chooses a default variable. WebBut the place of the constant doesn't matter. In the first evaluation of partial derivative respect to x => x^2y = 2xy because we are considering y as constant, therefore you may replace y as some trivial number a, and x as variable, therefore derivative of x^2y is equivalent to derivative of x^2.a which is 2a.x , substitute trivial a with y ...
