( 20 pts) Use the help function to get help about functions deg2rad and rad2deg. Take an angle of 90 degrees and convert it to radians. Take pi radians and convert to degrees. 5. ( 20 pts) (a) Create a variable named theta. Assign an angle of pi/6 to it. Prove the trigonometric identity sin2=2sincos Here the is the variable 'theta' you created. (b) Convert theta into degrees and store in a new variable theta d and then repeat (a) to prove the trigonometric identity again. (Do not use function deg 2 rad).
