`(tantheta)/(sectheta+1)+(cottheta)/(c o s e ctheta+1)=c o s e ctheta+sectheta-c o s e cthetasectheta`

If tan theta=1/sqrt7 ,then (c o s e c^2theta-sec^2theta)/(c o s e c^2theta+sec^2theta)=?

Prove: (cos e c\ theta-sectheta)(cottheta-tantheta)=(cos e c\ theta+sectheta)(secthetacos e c\ theta-2)\

(tantheta)/(sectheta-1)+(tantheta)/(sectheta+1) is equal to (a) 2tantheta (b) 2sectheta (c) 2\ cos e c\ theta (d) 2\ t a nthetasectheta

(tantheta)/(1-cottheta)+(cottheta)/(1-tantheta)=1+tantheta+cottheta=sectheta"cosec"theta+1

Prove that (costheta-sintheta+1)/(costheta+sintheta-1)=c o s e ctheta+cottheta

Prove that: (tantheta)/(1-cottheta)+(cottheta)/(1-tantheta)=1+secthetacos e ctheta

Prove that: sqrt((1+costheta)/(1-costheta))=cos e ctheta+cottheta .

If cos e ctheta-sin theta=m and sectheta-cos theta=n eliminate theta

Prove the following tantheta/(1-cottheta) +cottheta/(1-tantheta) =sectheta.cosectheta+1=1+tantheta+cottheta
