They are thinking of replacing all three of them with Pow The economy is so bad that the following is happening with Snap, Crackle and Pop They are thinking of replacing all three of them with Pow Kelloggs hired a “cereal” killer to kill them all Snap is spreading rumors that “Pop was a rolling stone” They are selling smack, crack and pot, respectively. http://nm.mathforcollege.com

7.02 Trapezoidal Rule http://nm.mathforcollege.com

The morning after learning trapezoidal rule… http://nm.mathforcollege.com

You are happy because You are thinking about your free will You are delusional You have to see my pretty face for only three more weeks All of the above http://nm.mathforcollege.com

Two-segment trapezoidal rule of integration is exact for integration of polynomials of order of at most 1 2 3 4 http://nm.mathforcollege.com

In trapezoidal rule, the number of segments needed to get the exact value for a general definite integral 1 2 1 googol infinite http://nm.mathforcollege.com

In trapezoidal rule, the number of points at which function is evaluated for 8 segments is 9 16 17 http://nm.mathforcollege.com

In trapezoidal rule, the number of function evaluations for 8 segments is 9 16 17 http://nm.mathforcollege.com

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. n 1 2 3 4 5 Value 16520 15421 15212 15138 15104 The number of significant digits at least correct in the answer for n=5 is 1 2 3 4 http://nm.mathforcollege.com

trapezoidal rule is most nearly The value of by using one segment trapezoidal rule is most nearly 201.33 212.00 424.00 742.00 http://nm.mathforcollege.com

The velocity vs time is given below The velocity vs time is given below. A good estimate of the distance in meters covered by the body between t=0.5 and 1.2 seconds is t(s) 0.5 1.2 1.5 1.8 v(m/s) 213 256 275 300 213*0.7 256*0.7 256*1.2-213*0.5 ½*(213+256)*0.7 http://nm.mathforcollege.com

A scientist would derive one-point Gauss Quadrature Rule based on getting exact results of integration for function f(x)=a0+a1x. The one-point rule approximation for the integral is http://nm.mathforcollege.com

For integrating any first order polynomial, the one-point Gauss quadrature rule will give the same results as 1-segment trapezoidal rule 2-segment trapezoidal rule 3-segment trapezoidal rule All of the above http://nm.mathforcollege.com

A scientist can derive a one-point quadrature rule for integrating definite integrals based on getting exact results of integration for the following function a0+a1x+a2x2 a1x+a2x2 a1x a2x2 http://nm.mathforcollege.com

For integrating any third order polynomial, the two-point Gauss quadrature rule will give the same results as 1-segment trapezoidal rule 2-segment trapezoidal rule 3-segment trapezoidal rule None of the above http://nm.mathforcollege.com

The highest order of polynomial for which the n-point Gauss-quadrature rule would give an exact integral is n n+1 2n-1 2n http://nm.mathforcollege.com

You are asked to estimate the water flow rate in a pipe of radius 2m at a remote area location with a harsh environment. You already know that velocity varies along the radial location, but do not know how it varies. The flow rate, Q is given by To save money, you are allowed to put only two velocity probes (these probes send the data to the central office in New York, NY via satellite) in the pipe. Radial location, r is measured from the center of the pipe, that is r=0 is the center of the pipe and r=2m is the pipe radius. The radial locations you would suggest for the two velocity probes for the most accurate calculation of the flow rate are 0, 2 1, 2 0, 1 0.42, 1.58 http://nm.mathforcollege.com

A scientist an approximate formula for integration as ,where The values of c1 and x1 are found by assuming that the formula is exact for the functions of the form a0x+a1x2 polynomial. Then the resulting formula would be exact for integration. http://nm.mathforcollege.com
