The morning after learning trapezoidal rule

Two-segment trapezoidal rule of integration is exact for integration of polynomials of order of at most A.1 B.2 C.3 D.4

In trapezoidal rule, the number of segments needed to get the exact value for a general definite integral A.1 B.2 C.1 googol D.infinite

In trapezoidal rule, the number of points at which function is evaluated for 8 segments is A.8 B.9 C.16 D.17

In trapezoidal rule, the number of function evaluations for 8 segments is A.8 B.9 C.16 D.17

The distance covered by a rocket from t=8 to t=34 seconds is calculated using multiple segment trapezoidal rule by integrating a velocity function. Below is given the estimated distance for different number of segments, n. n12345 Value The number of significant digits at least correct in the answer for n=5 is A.1 B.2 C.3 D.4

The morning after learning Gauss Quadrature Rule

is exactly A.. B. C. D.

A scientist would derive one-point Gauss Quadrature Rule based on getting exact results of integration for function f(x)=a 0 +a 1 x. The one-point rule approximation for the integral A.. B. C. D. is

For integrating any first order polynomial, the one-point Gauss quadrature rule will give the same results as A.1-segment trapezoidal rule B.2-segment trapezoidal rule C.3-segment trapezoidal rule D.All of the above

A scientist can derive a one-point quadrature rule for integrating definite integrals based on getting exact results of integration for the following function A.a 0 +a 1 x+a 2 x 2 B.a 1 x+a 2 x 2 C.a 1 x D.a 2 x 2

For integrating any third order polynomial, the two-point Gauss quadrature rule will give the same results as A.1-segment trapezoidal rule B.2-segment trapezoidal rule C.3-segment trapezoidal rule D.None of the above

The highest order of polynomial for which the n-point Gauss-quadrature rule would give an exact integral is A.n B.n+1 C.2n-1 D.2n
