Find the derivative of \( f(t) = (1 + \cos(t^2))^3 \).

OnlineGDB: LINK PythonOnline: LINK Write a function called most_frequent that takes a list of integers and returns the element that appears most frequently in the list. Note: The list will contain at least one element If multiple elements have the same highest frequency, return any one of them Example test cases: most_frequent([2, 3, 2, 4, 5, 2, 3])  # Expected output: 2# Explanation: 2 appears 3 times, 3 appears 2 times, 4 and 5 appear 1 time eachmost_frequent([7, 8, 7, 9, 8, 7]) # Expected output: 7most_frequent([1, 1, 2, 2, 3, 3])  # Expected output: 1 or 2 or 3 (anyone of them is acceptable)most_frequent([5, 5, 5, 5, 5])    # Expected output: 5most_frequent([10])    # Expected output: 10

What would be the output of the following code? numbers = [8, 15, 22, 9, 31]total = 0for n in numbers: if n > 10: if n % 2 == 1: total += 5 else: total -= 2 else: if n >= 8: total += n else: total -= 4print(total) 

What would be the output of the following code? a = {2, 4, 6, 8}b = {4, 6, 10, 12}u = a.union(b)i = a.intersection(b)a.add(14)combined = list(u.union(i))combined.sort()print(combined[2:6])
