`tan theta=(2x(x+1))/(2x+1)` then `sintheta=`

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-(1)/(4x), then sec theta-tan theta is equal to -2x,(1)/(2x) b.(1)/(2x),2x c.2x d.2x,(1)/(2x)

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 , show that sec theta = 1/2 (x +1/x) and tan theta = 1/2 (1/x -x) .

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

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

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

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

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