Question

2. (10 pts. Please perform the following calculations via MATLAB a. Calculate e3!/pi and round the answer to the nearest integer (all via MATLAB commands) b. Calculate cos(wt) for t (time) from 0 seconds to 10 seconds (with 1 second increments – created via colon operator) where w = 30°/seconds c. Please sort the values of the vector given below from smallest to largest and save it as another single column vector and G = [68, 83,61, 70, 75, 82,57,5, 76, 85,62,71,96, 78, 76, 68, 72, 75, 83,93] d. Find the mean of the values of vector G given in part o e. Form a vector that has the square roots of the values of vector G given in part c, sorted. f. Form a 5 column 7 row zeros matrix. g. Form a single row array that has 25 equally spaced points between 68.2456 and 98.1207. h. Form a 4 by 4 matrix that has random values. i. Create a new scaler called B and assign the value at second row and fourth column of the matrix you created for part h (not manually. Call the value using the address of the number in matrix) j. Plot the G array given in part c vs the array you formed in part e.
