Simplify `(sectheta-tantheta)^2`

Simplify (sintheta+sectheta)^(2)+(costheta+cosectheta)^(2) .

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

(tantheta-sectheta)^2

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

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

Simplified expression of (sectheta+tantheta)(1-sintheta) is __________.

Derivative of log(sectheta+tantheta) with respect to sectheta at theta=(pi)/(4)

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

sqrt(2)sectheta+tantheta=1

If sectheta=a+(1)/(4a) , and 0 < theta < pi/2 find sectheta+tantheta .
