If your code is MATLAB source, Please type: >> syms t >> y=(2*sin(2*pi*t)*exp(-0.1*t)+0.2*cos(20 *pi* t)) / (4-0.1*t+0.2*sin(10 *pi *t)) >> diff(y, 2)

I guess I have to get a polynomial interpolation and derive this polynomial. How can I get the polynomial interpolation of this function?
I found the 1st derivative: y | 0 | 0.005 | 10 f(t) | 0.05 | 0.0503 | 0.2271 Newton interpolation: Is correct ? For the second derivative I need to interpolate again?
I have an observation in this exercise that I did not understand. OBS: Use 0.005s step to derive
