## Derivative of (1/x)(cos(1/x)):

((1/x)*cos(1/x))'(1/x)'*cos(1/x)+(1/x)*(cos(1/x))'(((1)'*x-(1*(x)'))/(x^2))*cos(1/x)+(1/x)*(cos(1/x))'((0*x-(1*(x)'))/(x^2))*cos(1/x)+(1/x)*(cos(1/x))'((0*x-(1*1))/(x^2))*cos(1/x)+(1/x)*(cos(1/x))'(-1/(x^2))*cos(1/x)+(1/x)*(cos(1/x))'(-1/(x^2))*cos(1/x)+(1/x)*-sin(1/x)*(1/x)'(-1/(x^2))*cos(1/x)+(1/x)*-sin(1/x)*(((1)'*x-(1*(x)'))/(x^2))(-1/(x^2))*cos(1/x)+(1/x)*-sin(1/x)*((0*x-(1*(x)'))/(x^2))(-1/(x^2))*cos(1/x)+(1/x)*-sin(1/x)*((0*x-(1*1))/(x^2))(-1/(x^2))*cos(1/x)+(1/x)*(-1/(x^2))*(-sin(1/x))(-1/(x^2))*cos(1/x)+(1/x)*(sin(1/x)/(x^2))x^-3*sin(1/x)-(x^-2*cos(1/x))`
The calculation above is a derivative of the function f (x)
