If `tan^(-1)((3)/(4))=A` then `sin A`

If tan^(-1)((3)/(4))=A, then find the value of sin2A

If sin^(-1)alpha=tan^(-1)((3)/(4)), then alpha equals:

If: cos(tan^(-1)x)=sin (cot^(-1).(3)/(4)), then : x =

tan(sin^(-1) (4/5))

If x = sin (2tan ^ (- 1) 2), y = sin ((1) / (2) tan ^ (- 1) ((4) / (3))), then -

Evaluate each of the following: tan((tan^(-1)3)/(4))( ii) tan((sin^(-1)5)/(13))( iii) tan((cos^(-1)8)/(17))

tan [cos ^ (- 1) ((3) / (4)) + sin ^ (- 1) ((3) / (4)) - sec ^ (- 1) 3]

[sin(tan^(-1).(3)/(4))]^(2) =

if tan ((pi)/(4)+(y)/(2))=tan^(3)((pi)/(4)+(x)/(2)) then (3+sin^(2)x)/(1+3sin^(2)x)=
