You are required to calculate the gradients of $f(w,x)=\frac{1}{2+si{n}^2(w_1{x}_1)+cos(w_2{x}_2)}$

with respect to $w_i$ and $x_i.$

Use computational graph for calculation

Note:

Please use $w_1=\frac{}{2},x_1=1,w_2=\frac{}{2},x_2=2.$

For $f(x)=sin(x),f^{\text{'}}(x)=cos(x)$

For $f(x)=cos(x),f^{\text{'}}(x)=-sin(x)$

For $f(x)=x^2,f^{\text{'}}(x)=2x$

Task B: Please write a python program to implement the computational graph and verify your answer.
