Pove that-
`sectheta-tantheta=1/(sectheta+tantheta)=(1-sintheta)/costheta`

Prove that- (sectheta+tantheta-1)/(1-sectheta+tantheta)=(1+sintheta)/costheta

Prove that (1+sectheta-tantheta)/(1+sectheta+tantheta) = (1-sintheta)/(costheta)

Prove that- (sectheta+tantheta)/(sec-tantheta)=((1+sintheta)/costheta)^2

(tantheta/sectheta)=

tantheta-tantheta/2=sectheta/2

(tantheta-sectheta)^2

sqrt(2)sectheta+tantheta=1

Prove that : (i) (1)/(sectheta-tantheta)+(1)/(sectheta+tantheta)=2sectheta " " (ii) ("cosec "theta+cottheta)/("cosec "theta-cottheta)=("cosec "theta+cottheta)^(2)

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

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