Scilab Assignment

For this homework you will be graphing in SciLab. You will make a script for each of the problems below and will turn them in electronically to Moodle. Remember to name each plot, label the axis with the correct units, and include the grid. Points will be given for each of the items needed for a good graph. Review ICA # 8 for how to do the graphing in SciLab.

1. In HW#7 we created a script that created a row vector named ‘X’ that goes from 0 to 20 in increments of 0.5 and a row vector named ‘Y’ using the equation below. Write a SciLab script HW8_Prob_01.sce that will graph this information.

· Y=-0.45*X.^2+9.5*X

· Units are in feet.

2. In ICA #3 we graphed the path of a water balloon for our pressurized balloon launcher in Excel. For this problem we will be graphing the same information in SciLab. Write a SciLab script HW8_Prob_02.sce that will graph two functions on the same graph at the angles of 30 and 60 degrees.

· The launcher can launch a balloon at a velocity of 26.5 m/sec. Use the equations below for the path of the water balloon.

3. Write a SciLab script HW8_Prob_03.sce, that will graph each of the following equations using the subplot command.

· Radius = 0 to 10 cm in 0.1 cm increments.

· Volume of a cube = Radius3

· Area of a Circle = π*Radius2

· Perimeter of a Circle =2*π*Radius

· Volume of a Sphere = (4/3)*π*Radius3
