`costheta/sintheta/costheta/sintheta`

(costheta*csctheta-sintheta*sectheta)/(costheta+sintheta)

If (2sintheta-costheta)/(costheta+sintheta)=1 , then value of cottheta is :

Eliminate theta in the following (i) 2sintheta=x, 3costheta=y (ii) costheta + sintheta=x, costheta-sintheta=y

Evaluate costheta.costheta+sintheta.sintheta

costheta[(costheta, sintheta),(-sintheta,costheta)]+sintheta[(sintheta,-costheta),(costheta,sintheta)] is equal to (A) [(0,0),(1,1)] (B) [(1,1),(0,0)] (C) [(0,1),(1,0)] (D) [(1,0),(0,1)]

If (sintheta+costheta)/(sintheta-costheta)=3 then the value of sin^(4)theta is :

If (sintheta+costheta)/(sintheta-costheta)=3 and theta is an acute angle, then the value of (3sintheta+4costheta)/(8costheta-3sintheta) is

If (sintheta+costheta)/(sintheta-costheta)=3 , then find the value of sin^(4)theta-cos^(4)theta .

Express the following as a single trignometric ratio: sqrt3 costheta-sintheta sintheta-costheta .

If tantheta = frac{3}{4} then (4sintheta-costheta)/(4sintheta+costheta) is equal. to:
