4. Evaluate the function f(x)=x2e21xsin(x21) using numpy. Create a one-dimensional array x using either the linspace or arange function that starts with x=0 and ends at x= 4. The increment size is x=/800. Store the calculations of f(x) at each value of x in the variable f. Do not use a for or while statement in computing f(x). 5. Develop a series of statements to produce the following two-dimensional arrays in numpy. In solving this problem, do not use the np. array () function but instead consider the use of zeros, ones, arange, linspace functions as well as the reshape method and slicing operator.
