" 55.aff tan "theta+sec theta=x," तो रिड़ करें कि sin "theta=(x^(2)-1)/(x^(2)+1)

If tan theta+sec theta=x" show that 2 tan "theta=x -1/x, 2 sec theta=x+1/x. Hence show 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 sec theta+tan theta=x ,then find the value of (x^(2)-1)/(x^(2)+1)

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 4x = sec theta and (4)/(x) = tan theta then 8 (x^(2) - (1)/(x^(2))) is

If sec theta+tan theta=x, then sec theta=(a)(x^(2)+1)/(x) (b) (x^(2)+1)/(2x)(c)(x^(2)-1)/(2x) (d) (x^(2)-1)/(x)

If sec theta+tan theta=x, then tan theta=(x^(2)+1)/(x) (b) (x^(2)-1)/(x)( c) (x^(2)+1)/(2x) (d) (x^(2)-1)/(2x)

If 3x=sec theta,(3)/(x) =tan theta then (x^(2)-(1)/(x^(2))) I equal to:

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