Answer to Question #257464 in Math for asdgfhvlcmdbs

Question

1. What is the secant method formula for finding the square root of a real number R from the equation x2 − R = 0
2. Given one of the initial estimates is x₀ = 3, f (3) = 5, and the angle the secant line makes with the x-axis is 57°, what is the next estimate of the root, x­₁ using secant method and the equation is f(x) = 0
3. Given the equation and using the Naïve Gauss elimination method, solve the unknown and consider 4 significant digits in your answer.

0.0030x₁ + 55.23x₂ = 58.126.239x₁ – 7.123x₂ = 47.23
