3. 15 pts: Perform the steps below. a) Create a variable tempF to store the temperature in degrees Fahrenheit (32F). b) Suppress the output when you enter the value of tempF. c) Convert this to degrees Celsius (C) and store the result in a variable named tempC. C=(F-32)*5/9 4. 20 pts: Use the help function to get help about functions deg2rad and rad2deg. Take an angle of 45 degrees and convert them to radians. Take pi radians and convert to degrees. 5. 20 pts: (a) Create a variable named theta_d. Assign an angle of 60 degrees to it. Prove the trigonometric identity Here the is the variable 'theta_d' you created. (b) Convert the theta_d into radians and store in a new variable theta r and then repeat (a) to prove the trigonometric identity again. (don't use function deg2rad).
