03.05.1 Multiple-Choice Test Secant Method Chapter 03.05 1. The secant method of finding roots of nonlinear equations falls under the category of _____________ methods. (A) bracketing (B) graphical (C) open (D) random 2. The secant method formula for finding the square root of a real number R from the equation 0 2 = R x is (A) 1 1 + + i i i i x x R x x (B) 1 1 + i i i i x x x x (C) + i i x R x 2 1 (D) 1 1 2 2 + + i i i i i x x R x x x 3. The next iterative value of the root of 0 4 2 = x using secant method, if the initial guesses are 3 and 4, is (A) 2.2857 (B) 2.5000 (C) 5.5000 (D) 5.7143 4. The root of the equation ( ) 0 = x f is found by using the secant method. Given one of the initial estimates is 3 0 = x , ( ) 5 3 = f , and the angle the secant line makes with the x -axis is ° 57 , the next estimate of the root, 1 x , is (A) –3.2470 (B) –0.24704 (C) 3.247 (D) 6.2470
