Can someone who is knowledgeable in Python Programming Language please help provide the accurate formulas/codes for the following problems below:

a) Ask the user the input an angle between 0 and 90 degrees, then compute and display the cosine of that angle (remember to convert to radians!). If the user picks an angle outside of these bounds, inform them that the inputted angle is out of bounds. Do this while using if/else if/else.

b) Ask a user for three numerical inputs. Insert these inputs into an array, then display the array. Double the array and display the doubled array as well.

c) Create an array of ten numbers. Multiply each element by 2 and display both the original number and its double, with descriptive text telling the user what is happening.

d) Create an array of at least ten numbers. Square every number in that array and display the result for the user.

Thanks in advance and I will be sure to leave an upvote.
