(0)*tan((1)/(2)sin^(-1)(3)/(4))

Evaluate the following: (i) tan{2\ tan^(-1)(1/5)-pi/4} (ii) tan(1/2\ sin^(-1)(3/4)

Evaluate the following: (i) tan{2\ tan^(-1)(1/5)-pi/4} (ii) tan(1/2\ sin^(-1)(3/4)

Which of the following is not a rational number. a. sin (tan^(-1) 3 + tan^(-1).(1)/(3)) b. cos ((pi)/(2) - sin^(-1).(3)/(4))

Prove that : tan^(-1).(1)/(4)+tan^(-1).(2)/(9)=(1)/(2)sin^(-1).(4)/(5)

Show that cos(2Tan^(-1).(1)/(7))=sin(2Tan^(-1).(3)/(4))

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

tan^(-1)((1)/(2))+tan^(-1)((1)/(3))=(pi)/(4)|0tan(1)+tan(1)
