Question 1108758: re:interval
the interval 0≤θ≤π/2 was not given in the problem, it was given in the solution.
what i dont understand is how they got the interval (or the endpoints) from the function t(0)=2cos(0)+0
thanks!

If I understand the question properly, the intervals given for many trig functions are 0 to 2pi inclusive. After/Before that, if the function repeats, as this one does, it is usually not considered.
