Find the value of tan((1)/(2)cos^(-1)((sqrt(5))/(3)))

The value of tan[(1)/(2)cos^(-1)((sqrt(5))/(3))] is :

The value of tan[(1)/(2)cos^(-1)((sqrt(5))/(3))] is :

(i) If sin ^(-) x + sin ^(-1) y = pi//2 , then prove that : cos^(-1) x = sin^(-1) y (ii) Prove that : sin ((1)/(2) cos^(-1).(4)/(5))= (1)/sqrt(10) (iii) Prove that : tan ((1)/(2) cos^(-1).(sqrt(5))/(3)) = (3-sqrt(5))/(2)

tan((1)/(2).cos^(-1).(2)/(sqrt(5)))=

tan((1)/(2).cos^(-1).(2)/(sqrt(5)))=

tan[1/2cos^(-1)((sqrt(5))/3)]=

Evaluate: tan{(1)/(2)cos^(-1)((sqrt(5))/(3))}
