The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographical latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula:
d = radius * arccos(sin(x 1) * sin(x 2) + cos(x 1) * cos(x 2) * cos(y1 - y2))
Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,371.01 km. Note that you need to convert the degrees into radians using the math.radians function since the Python trigonometric functions use radians. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.
The quadratic formula is used to solve a very specific type of equation, called aquadratic equation. These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula
x = ( -b ± √( b^2 - 4ac ) ) / ( 2a )
Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of thediscriminant is positive then the equation has two real roots. If the value of thediscriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and then calculate the solution(s) of the equation. Do not calculate the solutions in the discriminant…
Part 1: Write a function factorialFunc(n) that gets the positive integer n and calculates n!
n! = n*(n-1)* (n-2)* (n-3) … * 3 * 2 * 1;
Part 2: sin(x) can be approximately calculated using the following formula, where n! is factorial(n) – for example 3!=3*2*1 = 6 (the function in previous problem).
The more terms we use in the series, the higher will be accuracy of the calculations. By using infinite terms in the series we will have the exact value.
Write a program that gets x and calculates sin(x) using 5, 10, 20 terms, using C++

- Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3.

Note that the result won't be exact due to computer limitations of storing all decimal values. Use the round() function (e.g. round(12.4) results in 12 and round(12.5) results in 13) Note 1 Import math package inside the function and use math.sqrt() function. Note 2 There is no need to ask for input or print the output. Just submit the function with the following format: Соpy def fib(int1): # Your code here where int1) is a nonnegative integer.
