(5) `sec theta+tan theta=7` then `sec theta-tan theta=?`

If theta is eliminated from the equations a sec theta-x tan theta=y" and "b sec theta+y tan theta=x (a and b are constants), then :

If 1+ tan^(2) theta = sec^(2) theta then find (sec theta + tan theta)

If pi/2 < theta < (3pi)/2 then sqrt ((1-sin theta)/(1+sin theta))= a. sec theta-tan theta, b. sec theta + tan theta, c. tan theta-sec theta, d. none of these

Prove that : ( sin theta- cos theta +1)/( sin theta +cos theta -1) = (1)/( sec theta - tan theta)

If sec theta+tan theta=(1)/(2) The value of sec theta=

If sec theta+tan theta=(1)/(2) The value of tan theta =

Prove that : (tan theta)/(1 -cot theta) + (cot theta)/(1- tan theta) = 1 + sec theta cosec theta

(2sec theta+3 tan theta+5 sin theta -7cos theta+5)/(2tan theta+3 sec theta+5 cos theta +7sin theta+8)= (a) tan (theta/2) (b) cot (theta/2) (c) sec (theta/2) (d) cosec (theta/2)

General solution of tan theta+tan 4 theta+tan 7 theta=tan theta tan 4 theta tan 7 theta is

Prove that (sec theta+tan theta -1)/(tan theta -sec theta +1)=cos theta/(1-sin theta)
