The independent variable x, in the function y = f(x) is called as

• variable
• entry
• argument
• constant

If the nth differences of a tabulated function are constants, then the function is a polynomial of degree

• 1
• 2
• n-1
• n

Newton’s forward interpolation formula cannot be used for interpolating

• Unequal intervals
• Outside the interval
• A value of y nearer to the end of the table of values
• A value of y nearer to the beginning of the table of values

The first two terms in the Newton-Gregory forward interpolation formula will give

• Linear interpolation
• Parabolic interpolation
• Hyperbolic interpolation
• Cubic interpolation

The principle of method of least squares states that the best fitting curve to the set of points is that for which the sum of squares of residual is

• Maximum
• Minimum
• Less than Zero
• Greater than Zero

If the sum of squares of residual is zero, then the given set of points lie

• Above the Curve
• Below the Curve
• On the Curve
• Near the Curve

The condition for convergence in Gauss-Seidel method is

• the number of unknowns is not equal to the number of equations
• all equations are need not be linear
• the coefficient matrix should be a rectangular matrix
• the coefficient matrix should be diagonally dominant

Newton’s method is applicable to the solution of

• Algebraic and Transcendental Equations
• Algebraic Equations alone
• Transcendental Equations alone
• Linear Equations only
