Question 1 Create a SINE wave in Octave that has 200 vector elements on its X axis. Create a COSINE wave with 200 Vector elements on its X axis. Show both the SINE wave and COSINE Wave on the same plot. The Plot should have a title and label on both the X and Y axes. Question 2 Write a small program in Octave which asks the user to give 5 numbers between 0 and 100 and prints the AVERAGE/MEAN of those numbers. You must use a for loop and the commands: input() and printf() or disp(). Question 3 Consider the marks of 8 students in Project scenario: 10, 6.7, 13.7, 12, 11, 10.7, 9, 11.2. The AVERAGE marks of the class is 10.54. Write a small program in Octave that sets a variable MEAN to 10.54 then asks the user to input the students' marks, and then prints the VARIANCE of the numbers. You must use a for loop and the commands: input() and printf() or disp()
