IN MATLAB:
Consider the function 
c(x)=x4−5x2+4. Find the zeros of the
function, then print the results to the Command Window.
Suggestion: You may find it helpful to plot the
graph first to get a feel for where the zeros exist; there are
exactly 4 zeros for this function.

In MATLAB please
Consider the nonlinear function: y = f(x) = x3 cos x a. Plot y as a function of x as x is varied between -67 and 67. In this plot mark all the locations of x where y = 0. Make sure to get all the roots in this range. You may need to zoom in to some areas of the plot. These locations are some of the roots of the above equation. b. Use the fzero...
