expand ex sin y using the maclaurins theorem up to 3rd term degree
the Maclaurin expansion of any two-variable function is given by the formula shown above. To determine the first-degree Taylor polynomial linear approximation, we first compute the partial derivative fx(x,y) and fy(x,y). we Then evaluate these partials and the function itself at the point (0,0).
To determine the second-degree Taylor polynomial (quadratic) approximation, we need to evaluate the send partial derivatives of the function and evaluate the derivatives at point(0,0) this can be clearly seen in the image below:
the expansion of ex sin y using the Maclaurin theorem up to the 3rd term therefore becomes:
