[cos(540^(@)-theta)-sin(630^(@)-theta)" is equal to "],[[" (a) "0," (b) "2cos theta],[" (c) "2sin theta," (d) "sin theta-cos theta]]

(tan(-theta))/(sin(540^(@)+theta))

(cos theta+cos3 theta)/(sin theta-sin3 theta) is equal to:

If sin theta+cos theta=1, then sin theta cos theta is equal to :

If 2 sin theta=5 cos theta , then (sin theta+cos theta)/(sin theta-cos theta) is equal to: यदि 2 sin theta=5 cos theta है, तो (sin theta+cos theta)/(sin theta-cos theta) का मान किसके बराबर होगा ?

If a cos theta - b sin theta =c, " then" a sin theta + b cos theta is equal to

If 3sin theta+4cos theta=5 then 4sin theta-3cos theta is equal to

(cos theta)/(1 - sin theta) + (cos theta)/( 1 + sin theta) equals
