In this question you compare numerically polynomial interpolation at equally spaced points, polynomial interpolation at the chebyshev points, and cubic spline interpolation. (a) first write a routine that does the following: given an interval [a, b], a function f, and a number n, your code should produce the following three interpolants to the function f: (i) a polynomial interpolant to f at n equidistant points on [a, b]; (ii) a polynom

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
