I just wanted to know if my answer to this problem is accurate:
2 degree taylor approximation around (0,0) for the following function:
f(0,0) + fx(0,0)x + fy(0,0)y + 1/2 fxx(0,0)x^2 + 1/2 fyy(0,0)y^2 + fxy(0,0)xy
Also, can someone post the general form for a multivariable taylor expansion?
The Taylor series for the function of two variables, f(x,y), around the point [tex](x_0,y_0), is:
For positive integer n, there are n+ 1 "nth" derivatives to be evaluated at . Each will involve f differentiated with respect to x i times and with respect to y n- i times for i= 0 to n. Each is divided by n! and multiplied by .
