Write a function that computes accurately values of f(x) = ^4 squareroot x + 4 -...
How can values of the function f(x)=cos(2+x) be accurately computed for values of x close to 0?
in C++. Write a function squareRoot that uses the Newton’s method of approximate calcu-lation of the square root of a number x. The Newton’s method guesses the square root in iterations. The first guess is x/2. In each iteration the guess is improved using ((guess + x/guess) / 2 ) as the next guess. Your main program should prompt the user for the value to find the square root of (x) and how close the final guess should be to...
17. In the function f(x) = a(x + 2)(x - 3)', a and b are both integer constants and b is positive. If the end behavior of the graph of y = f(x) is positive for both very large negative values of x and very large positive values of x, what is true about a and b? A. a is negative, and b is even. B. a is positive, and b is even. a is negative, and b is odd....
1. (a) We need to calculate accurate values of the function for very large values of x. However, it is found that just programming this formula into a computer gives very poor accuracy for large x Explain why this happens, and show how to re-write the function so that it can be used reliably, even when x is large. [6 points] (b) In diffraction theory, it is sometimes necessary to evaluate the function sin θ f(x) for small to moderate...
Use the second Taylor polynomial of f(x) = squareroot of x at x=9 to estimate squareroot of 9.4
Write a function that accepts as input a scalar x and an integer
n and computes f(x), where
f(x) = 1 + x + ... + x^n.
For example, if x = 2 and n = 3, the function should return 1 +
2 + 4 + 8 = 15.
Hint: Use point-wise operations and the MATLAB sum function.

Consider the equation f(x) = 2*sin(pi*x) + 3*cos(pi*x) Write a c program that computes the values of f(x) for the following values of x: 0.25, 0.5, 1, 2. Your program should allow the user to enter the value from the standard input and the results will be displayed as follows: /*****************************************************************/ Value of x Value of f(x) 0.25 3.5355 0.5 1 2

3. Near certain values of r each of the following functions cannot be accurately computed using the formula as values of r which are involved (e.g. pose a reformulation of the function (e.g., using Taylor series, rationalization, trigonometric identities, etc.) to remedy the problem. This is problem # 12 from the textbook. Please also see pages 48-49 for examples and more details. given due to cancellation error. Identify the near z 0 or large positive r) and pro- (a)...
Homework 4 - False Position Find the zeros of the function f(x) within the interval (-4, 6) using the False Position method with f(-4) > 0 what you must know before you start working on the homework: f(-1) <0 f(x) = sin(21(x/5) + exp(x/5) f(+6) > 0 (a) Write a Matlab function that computes the values for f(x) when xis given as an input.
