Total Marks: 20
Due Date: 8th June, 2022
DON’T MISS THESE: Important instructions before attempting the solution of this assignment:
• To solve this assignment, you should have good command over 1-8 lectures.
• Upload assignments properly through the LMS, No Assignment will be accepted through email.
• Write your ID on the top of your solution file.
Don’t use colored backgrounds in your solution files.
Use Math Type or Equation Editor, etc. for mathematical symbols.
You should remember that if the solution files of some students are finding the same (copied), we will reward zero marks to all those students.
Make a solution by yourself and protect your work from other students, otherwise both original and copied assignments will be awarded zero marks.
Also remember that you are supposed to submit your assignment in Word format, any other format like scanned images, etc. will not be accepted and be awarded zero marks
Question 1
Find a real root of the equation 2x+cos(x)+e^x=0
using Bisection Method
using Newton Raphson Method
Also compare the results and comment which of the methods performs better and which is worst.
You will consider x_0=-0.6557 as a best approximation while comparing the roots.
Note:
In each of the above methods,you are required to perform three iterations.

k2 = 45(-12.30-42)In the fourth-order Runge-Kutta method,  is computed using the following formula:

k_2 = h \cdot f\left( t_n + \frac{h}{2}, y_n + \frac{k_1}{2} \right)where:
•  h is the step size •  t_n is the current value of the •  y_n is the current value of the dependent variable, •  k_1 = h \cdot f(t_n, y_n) is the first slope.The formula you provided seems to be incorrect or misformatted. If you have specific terms or a function f(t, y) , please clarify or correct the notation so I can provide the accurate calculation for  in your context.
