If you can program a calculator or computer, estimate the length of the curve f(x) on the given interval using largest n's. f(x)=56cos(x), for x is greater than/equal to 0 and x is smaller than/equal to pi/2.

estimates, using values of n from 5 to 50: 5: 56.0341 10: 56.0401 15: 56.0434 20: 56.0456 25: 56.0471 30: 56.0483 35: 56.0491 40: 56.0498 45: 56.0503 50: 56.0507 wolframalpha.com calculates 56.0528 just type in arc length 56cos(x), x = 0 .. pi/2

THANK YOU!!!!!
