Yeah that's precisely what I did. Ok that's alright then, I can definitely cope with 1 mark lost.
Although, because it asked for the time difference between the 1st and 2nd times they are equal, surely that will be the difference between when t=pi/6 and t=3pi/2 ? As 5pi/6 would be the third time they are equal to each other

5pi/6 is smaller than 3pi/2 so would occur first but its only one mark so no major issueee
