यदि `tan theta + sec theta=l` तो सिद्ध करें `sec theta=(l^(2)+1)/(2l)`

if tan theta+sec theta=l then prove that sec theta=(l^(2)+1)/(2l)

if tan theta+sec theta=l then prove that tan theta=(l^(2)+1)/(2l)

prove that (tan theta) / (sec theta -1) = (tan theta + sec theta + 1) / (tan theta + sec theta - 1)

( tan theta)/( sec theta -1)-(tan theta )/( sec theta + 1)=

If sec theta + tan theta = 1/2 , then sec theta =………

If tan theta + sec theta = n, then sec ^(4) theta - tan ^(4) theta- 2 sec theta tan theta =

tan2 theta(sec8 theta-1)=tan8 theta(sec4 theta-1)

l tan theta+m sec theta=n,l'tan theta-m'sec theta=n' Prove [(nl'-ln')/(ml'+m'l)]^(2)=1+[(m'n+mn')/(lm'+l'm)]^(2)

If sec theta- tan theta= P , then cosec theta = ? यदि sec theta- tan theta= P , है, तो cosec theta = ?

If sec theta+tan theta=2 , then sec theta-tan theta = ?
