.
Given that t lies in the interval[0,r/2] and that sint=1/3 determine each of the following:

a)cost
b)sect
c)cott
----------------------------------------


r is {{{pi}}}.


cost = {{{sqrt(1-sint^2)}}}.


sect = {{{1/cost}}}


ctt = {{{cost/sint}}}.


It is terrible how you did write your request.


I responded you in the same style.
