Question: USING MATLAB please show all commands (sin x + cos x)^2 = 1 + 2sin xcos x (b) 1 - 2cos x - 3cos^2 x/sin^2

USING MATLAB

please show all commands USING MATLAB please show all commands (sin x + cos x)^2

(sin x + cos x)^2 = 1 + 2sin xcos x (b) 1 - 2cos x - 3cos^2 x/sin^2 x = 1 - 3cos x/1 - cos x For each part, verify that the identity is correct by calculating the values of the left and right sides of the equation, substituting x=20 degree
