Choose the correct answer in each of the following questions: If sin theta=(a)/(b) " then " cos theta=?

If sin theta=(a)/(b) , then cos theta and tan theta in term of a and b are

Given that sin theta=(a)/(b then cos theta=

If (cos^(2) theta)/(a) = (sin^(2) theta)/(b) then (cos^(4) theta)/(a) + (sin^(4) theta)/(b) =

If theta be a positive acute angle and tan theta=(a)/(b) , then find the value of (a sin theta-b cos theta)/(a sin theta+b cos theta).

If tan theta=(a)/(b), prove that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))

If tan theta=(a)/(b), show that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))

If (x)/(a) cos theta + (y)/(b) sin theta = 1 , (x)/(a) sin theta - (y)/(b) cos theta =1 then

If tan theta=(a)/(b) such that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))^(k) then k is ?
