Solve `(tantheta-cottheta)^2=0`

If theta epsilon (0, pi/2) then the value of |((sintheta+cosectheta)^2, (sintheta- cosectheta)^2,1 ),((costheta+sectheta)^2, (costheta-sectheta)^2, 1),((tantheta+cottheta)^2, (tantheta-cottheta)^2, 1)|= (A) sintheta+costhetas+tantheta (B) 1 (C) 0 (D) 4

Solve: tan^(3)theta-3tantheta=0

Solve: tan3theta+tantheta=0

Solve: cot2theta=tantheta

If (tantheta+cottheta)/(tantheta-cottheta)=2,(0^(@)lethetale90^(@)) , then the value of sintheta is

Solve: cot\ theta/2-cottheta=cosec\ theta/2

((1-tantheta)/(1-cottheta))^(2)+1=

(cosectheta-sintheta)(sectheta-costheta)(tantheta+cottheta)=?

(csctheta-sintheta")(sectheta-costheta)(tantheta+cottheta)=
