To use Newton's method to solve the equation f(x) = x^4 - x^3 + 4x^2 - cos(x), you can follow these steps in MATLAB:
main.m58 chars4 lines
main.m61 chars4 lines
Choose an initial guess, let's say x0 = 0.
Iterate the following formula for 5 iterations (or any desired number of iterations):
main.m50 chars5 lines
After the 5 iterations, the variable x will contain the approximate solution to the equation f(x) = 0 using Newton's method.
Note that the above code assumes that the Newton's method will converge to a solution. If the function has multiple solutions or the initial guess is not close enough to a solution, the method may not converge or converge to a different solution.
Also, make sure to adjust the number of iterations, initial guess, and any other parameters as needed for your specific problem.
