The estimation of the value of a function at a point beyond the interval in which the data lies is called known as Interpolation why?
I have two functions in a function, one has a time complexity of O(n) and the other one has a time complexity of O(n^2). what is the overall time complexity of the function?
def function():
def function1():
def function2():
Given a vector of real numbers r = (r1, r2, ..., rm). We can standardize the vector using the formulation: vi = "im, where m
ri-m
is the mean of the vector r, and s is the standard deviation of r. The vector v = (v1, v2, ..., Un) will be the scaled vector.
Write a Python function scale_vec (r) that takes the vector r as input and returns the scaled vector v.
Sample inputs and outputs:
● Input: np.array([1, 3, 5]), output: [-1.22474487 0. 1.22474487]
• Input: np. array([3.3, 1.2, -2.7, -0.6]), output: [1.35457092 0.40637128 -1.35457092
-0.40637128]
Hint: Use numpy.mean and numpy.std with default parameters.
# Write your function here.
Let's test your function.
[ ] import numpy as np
print (scale_vec (np.array([1, 3, 5])))
print (scale_vec (np.array([3.3, 1.2, -2.7, -0.6])))

Write a function trapezint(f, a, b) that returns this approximation to the integral. Test your code by integrating cos(x) and sin(x) from 0 to π.arrow_forward

The key idea is to evaluate the growth of a function. For example, she now knows that n² grows faster than n. She wants to know whether she really understands the idea, so she has created a little task. First of all, she found a lot of functions here: 91 3n log n² 92: n! log(n!) 93 911 √n 912 log log n 98 2n+1 913 (n+1)! 918 nlogn 99 ln ln n 914 Vlogn 919 5n² 13n+6 910: 10000 915 log √n 920 n/logn Note: log n = log₂ n; ln n = log n; log² n = = (log n)²; n! is the factorial of n, i.e., n! = 1 × 2 × · • × n. Reading the long list, Yihan realized that things were not as simple as she thought. Could you help her with the following problems? For all the questions in this problem, you only need to show your answer without explaining. The only exception is question (4), where you need to show proofs or explanations.
