Question

By following the Solutions of Equations: Newton's Method, kindly answer only Item No. 1. a.), b.) and c.). Thank you.

Chapter V.
Solution of Equations: Newton's Method
Elementary Methods:
a) factoring b) completing squares c) quadratic formula
x= -b+Vb? -4ac
2a
d) synthetic division
Newton's Method: it can be made to yield a root to any desired degree of accuracy;
it is useful in obtaining approximations to imaginary roots, as
well as real roots of equations.
Formula:
Let f(x) = 0
y = f(x)
*x2 = X- f(x)
f'(x1)
steps: to find the roots using Newton's method
1) assign values of x to solve for y
2) plot the two consecutive points whose ordinates one is positive and the
other is negative
3) join the two points, taking the value of x where the line crosses the
x=axis as the first approximation for x(x1)
4) to find the other approximation for x use formula * until the difference
between the two consecutive approximations are nearly negligible.
Note:
X = first approximation of x (from the graph)
f(x1) = the value of f(x) at x = x1
f'(x) = the value of the first derivative of the function of x at x = x
Exercises: 1
1. Find the roots:
a) cube root of 98
2. Find to two decimal places the positive root of x'+x -3=0
3. Find to three decimal places the real roots of x'+3x-2=0
4. Find, in inches, the radius of a sphere of volume 1 cu. ft.
5. A hallow sphere of outer radius 10 in. weighs one-fifth as much as a solid
sphere of the same size and material. Find the inner radius.
6. A metal sphere of radius 2 in. is recast in the form of a cone of height 2 in.
surmounted by a hemisphere of the same radius as the cone. Find the radius of
the cone.
b) square root of 242
c) v80
7. A torpedo has the longitudinal section shown. When submerged, it displaces a
volume of water equal to a sphere of radius 1 ft. Find r in ft.
