If `tan theta = (20)/(21),` then `cos theta` is equal to

If sec theta +tan theta =P , then cos theta is equal to

If sec theta-tan theta=3 , then cos theta is equal to: यदि sec theta-tan theta=3 , है, तो cos theta बराबर है:

if tan theta=(a)/(b), then cos2 theta+a sin2 theta equal to

If sin theta = cos (20^(@)+theta) , then theta is equal to :

If 29 tan theta = 31 then the value of (1 +2 sin theta cos theta)/(1- 2 sin theta cos theta) is equal to

If tan theta+sec theta=e^(x) then cos theta equals

If tan theta=3/4 , then (4 sin theta- cos theta)/(4 sin theta+ cos theta) is equal to: यदि tan theta=3/4 , है, तो (4 sin theta- cos theta)/(4 sin theta+ cos theta) का मान किसके बराबर होगा ?
