`(sectheta+tantheta)/(sectheta-tantheta)+(sectheta-tantheta)/(sectheta+tantheta)`

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

Prove the following identities: (frac(1-sectheta+tantheta)(1+sectheta-tantheta))=(frac(sectheta+tantheta-1)(sectheta+tantheta+1))

Prove that sqrt((sectheta-tantheta)/(sectheta+tantheta))=sectheta-tantheta .

Prove that: (sectheta-tantheta)/(sectheta+tantheta)=1-2sectheta.tantheta+2tan^(2)theta

If tantheta+sectheta=8 then sectheta-tantheta is

(tantheta-sectheta)^2

If cottheta-tantheta=sectheta then theta =

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

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

Prove tantheta/(sectheta-1)+(tantheta)/(sectheta+1)=2cosectheta .
