Simplify `1-tantheta.tantheta`

tantheta . Cot theta =

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

sectheta/tantheta=?

(sin theta[(1-tantheta)tantheta+sec^(2)theta])/((1-sin theta)tantheta(1+tantheta)(sec theta+tantheta)) is equal to :

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

(tantheta/sectheta)=

(tantheta-sectheta)^2

Solve: cot2theta=tantheta

If sectheta+tantheta=5 , then the value of (tantheta+1)/(tantheta-1) is

frac(sintheta [(1-tantheta) tan theta+sec^2 theta])((1-sintheta) tantheta(1+tan theta) (sec theta+tantheta)) =?
