In: Advanced Math
Use (a) the Trapezoidal Rule, (b) the Midpoint Rule, and (c)
Simpson’s Rule to approximate the given integral with the specific
value of n. (Round your answer to six decimal
places).
∫13 sin (?) / ? ?? , ? = 4
Please show all work.
Here we take the partition {1,(3/2),2,(5/2),3} of [1,3] to proceed.
Approximation by Trapezoidal Rule for n=4
By trapezoidal rule we have
Here
Where (The width of the sub-intervels)
Approximation by Mid-point rule for n=4
By mid point rule
Where
are the mid points of the
subintervel.
Here ,
where and
So,
Approximation by Simpson’s Rule for n=4
By simpson's rule,
