`tan^(-1)(tanpi/(3))`

Find the value of: i) sin^(-1)(sinpi/3) ii) cos^(-1)(cos(2pi)/3)) , iii) tan^(-1)(tanpi/4)

tan^(-1)2-tan^(-1)1=tan^(-1)((1)/(3))

Prove that 3tan^(-1)((1)/(2+sqrt(3)))-tan^(-1)((1)/(2))=tan^(-1)((1)/(3))

tan^(-1)2-tan^(-1)1=tan^(-1)(1)/(3)

tan(tan^(-1)((1)/(2))-tan^(-1)((1)/(3)))=

"tan"^(-1)((1)/(3))+ "tan"^(-1)((2)/(9)) + tan^(-1)((4)/(3^(3))) + ....oo is equal to

If 3tan^(-1)(2-sqrt(3))-tan^(-1)(x)=tan^(-1)((1)/(3)) then x=

general solution of sec theta=(tan^(-1)(1)+tan^(-1)(2)+tan^(-1)(3))/(tan^(-1)1+tan^(-1)((1)/(2))+tan^(-1)((1)/(3))) is theta=

Prove that : tan^(-1) 1 + tan^(-1) 2 + tan^(-1) 3= pi = 2(tan^(-1) 1 + tan^(-1)((1)/(2)) + tan^(-1)( (1)/(3)))

general solution of sec theta=(tan^(-1)(1)+tan^(-1)(2)+tan^(-1)(3))/(tan^(-1)1+tan^(-1)((1)/(2))+tan^(-1)((1)/(3))) is theta=
