Simplify :
`tantheta / ( tantheta - 1 ) + 1/( tantheta ( 1 - tantheta ))`

tantheta . Cot theta =

(tantheta+2)(2 tantheta+1)= ?

sectheta/tantheta=?

sec^2theta/tantheta=?

(tan^(3)theta-1)/(tantheta-1) = ________.

tantheta .tan(90^(@) - theta) =

(sectheta+tantheta-1)(sectheta-tantheta+1)=

Simplify tan theta [(sectheta,tantheta),(tantheta,-sectheta)]+sectheta[(-tantheta,-sectheta),(-sectheta,tantheta)]

(tantheta+sectheta-1)/(tantheta-sectheta+1)=

(tantheta+sectheta-1)/(tantheta-sectheta+1)=
