" If "tan theta=(2x(x+1))/(2x+1)" then "sin theta=

If Tan theta = (2 x(x+1))/(2x+1) then Sin theta =

If tan theta=((2x)(x+1))/(2x+1), find sin theta and cos theta

if tan theta=(x)/(y) then sin2 theta+cos2 theta is

If sec theta=x+(1)/(4x), then prove that sec theta+tan theta=2x or (1)/(2x)

If cos@ theta - sin^2 theta = 1/x , (x > 1), then cos^4 theta - sin^4 theta = _________________

tan theta+sec theta=x show that 2tan theta=x-(1)/(x),2sec theta=x+(1)/(x) hence prove that sin theta=(x^(2)-1)/(x^(2)+1)

If sec theta+tan theta = x , prove that sin theta= (x^2-1)/(x^2+1)

If theta is an acute angle and sin((theta)/(2))=sqrt((x-1)/(2x)) ,then tan theta is equal to
