Introduction
 It is the study of algorithms that use
numerical approximations.
This gives solutions for complex problems.
This uses simple mathematical operations.
Muller Method
•It obtains a root
estimate by projecting
a parabola to the x-axis
through three function
values.

Chebyshev Method
It is an iterative method for
determining the solutions for the
system of linear equations.
This method is named after Russian
mathematician ‘Pafnuty Chebyshev’.
FORMULA FOR CHEBYSHEV
METHOD
Fixed Point Iteration Method
It is a method for solving the equations
of the form f(x)=0 & this is transformed
to by making the initial guess of
x0,the approximations of x1,x2,… are
computed by iteration form.
FORMULAE FOR FIXED
POINT ITERATION METHOD
Aitken’s Delta Square Method
This is a series acceleration method
used for accelerating the rate of
convergence of a sequence.
This method is named after Alexander
Aitken.
FORMULAE FOR AITKEN’S
DELTA SQUARE METHOD
Birge Vieta Method
•Used for finding roots of polynomials
functions.
•It uses synthetic division of a
polynomial to extract factor of the
given polynomial in the form of (x-p).
FORMULA FOR BIRGE
VIETA METHOD
Bairstow Method
It is an efficient algorithm for finding
roots of real polynomial of arbitrary
degree.
 The algorithm find the roots in
complex conjugate pairs using only real
arithmetic.

Advantages Of Numerical Methods
 We can solve complex problems with simple
operations.
 In many problems , analytical methods fail,
in such cases numerical methods works out
to be very well.
Disadvantage Of Numerical
Methods
It gives approximate solutions but not
the exact solutions.
APPLICATIONS OF
NUMERICAL METHODS
 Weather Predictions
 Vehicles By Using Computer Simulation.
 Spacecrafts
 In private investment funds for calculating
stock values.
 In airlines for fixing air fares & fuel prices.

PREDICTIONS
Conclusions
 For finding roots & numerical optimization.
 We can estimate solutions for linear & non-
linear equations.
