student : yes
student : I have a math problem that says find all points that are on y=tan x on the interval pie/2 , 3pie and have a y coordinate of 1/-square root of 3
student : i dont know how to solve it
tutor3 : ok
tutor3 : in the problem it is given y=tanx. and y=1/sqrt(3) right?
tutor3 : so we have to find x
tutor3 : so tanx=1/sqrt(3) =tan30 =tan(pie/6)
tutor3 : =pie/6
tutor3 : nterval(pie/2,3pie)
tutor3 : dd u get it?
student : do you have pie over 6 but how did u get pie over to and 3 pie
student : I meant I get pie over 6 but how did you get pie over 2 and 3 pie
tutor3 : pie/2 and 3pie is the interval
tutor3 : ll lie
tutor3 : where the value of x will lie
tutor3 : here value of x is pie/3 which lies in the interval
student : so the point is just pie/3,1/-sqrt of 3
tutor3 : yes because they have given only one cordiante of y
tutor3 : which is 1/sqrt3
tutor3 : did you get it?
student : one sec
student : ok
