Need help coding assignment

(a) Create a variable named theta. Assign an angle of pi/4 to it.

Prove the trigonometric identity sin^2(Theta)+cos^2(Theta)= 1

Here the (Theta) 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 deg2rad).
