Update : Correcgtion
if you meant
sqrt(3) * sin(t) = cos(t)
divide both sides by sin(t)
sqrt(3) = cos(t)/sin(t)
so this is
cot(t) = sqrt(3)
cos( pi/6) = sqrt(3)/2
sin(pi/6) = 1/2
so
cotan(pi/6) = sqrt(3)
since cotangent has period of pi
t = pi/6 and 7pi/6

sqrt(3) * sin(t) = cos(t)
Divide it by 2.
sqrt 3/2 sin t =1/2 cos t
Now replace the values
cos t cos 60 - sin 60 sin t=0
cos (t+60)=0=cos 90
This gives t+60=90, t=30 degrees.

sint = cost
sint = sin (90° - t)
t = 90° - t
t + t = 90°
2t = 90°
t = 45°.

√3.sin(t) = cos(t)
sin(t)/cos(t) = 1/√3
tan(t) = 1/√3
t = (π/6) + kπ ← where k is an integer
First case: k = 0 → t = π/6
Second case: k = 1 → t = (π/6) + π = 7π/6
Third case: k = 2 → t = (π/6) + 2π = 13π/6 → over 2π
→ Solution = { π/6 ; 7π/6 }

Ans. sqr(3)sin(t)=cos(t)=>sin(t)/cos(t)=1/sqr(3)
=>tan(t)=1/sqr(3)=>t=pi/3, pi+pi/3=4pi/3.
