There is no solution.

#sin theta = 1/(csc theta)#

#sin theta = 2/sqrt3 = 2/1.73 #

#= 1.15 > 0#

Therefore, there is no such angle #theta# that has sin > 1.

There is no such angle #theta# and we do not have a solution.

As the trigonometric ratios cosecant and secant cannot have their absolute value less than one

i.e. #|csctheta|>=1# and #|sectheta|>=1#

However, here #csctheta=sqrt3/2=1.732/2=0.866<1#

and #sectheta=sqrt3/3=1.732/3=0.5773<1#

There is no such angle #theta# and we do not have a solution.
