Question 28 of the TSPSC Manager (Engineering), HMWSSB, 2015: Paper 2 (Civil Engineering) (1 November 2015). Try it first, then open the answer and explanation.
In Simpson's formula for areas calculation, the line joining the top of the ordinates is considered as
- elliptical
- circular
- parabolic
- straight
Show answer
Answer: (3) parabolic
Simpson's one-third rule assumes that the boundary between every three consecutive ordinates is an arc of a parabola. The trapezoidal rule instead assumes straight lines between the tops of adjacent ordinates.
