Using Matlab and GUI function

Define a variable named "angle" to be 45 degree. Convert "angle" to radians using the following: Radians = degrees * (pi/180) Store the result in the variable "angleRad". Use the predefined variable "pi" in your calculation. Repeat the calculation for angle = 60 degree, 75 degree, and 90 degree. Using the "angleRad" you defined in problem 1, find the cosine and sine of "angle". Show the results in variables "cosAngle" and "sinAngle", respectively. Using variables "cosAngle" and "sinAngle", define the following: z = cos^2 (alpha) + sin^2 (alpha) A well-known identity in trigonometry is that the sum of cosine squared and sine squared of an angle always equals one. If your result for z was not one, review and redo the operations. Test your code for alpha = 45 degree, 60 degree, 75 degree, and 90 degree
