Second derivative y = cos ^ 2x. INX + e ^ (- x ^ 2)

Second derivative y = cos ^ 2x. INX + e ^ (- x ^ 2)

The second derivative is: 2 * sin (x) ^ 2 * log (x) - 4 * cos (x) / X * sin (x) - 2 * cos (x) ^ 2 * log (x) - cos (x) ^ 2 / x ^ 2-2 * exp (- x ^ 2) + 4 * x ^ 2 * exp (- x ^ 2). I used Matlab to find it for you. This is the source program. You can see if it is clearsyms x y; y = cos (x) * cos (x) * log (x) + exp (- x ^ 2)
