3tan^(-1)((1)/(2))+2tan^(-1)((1)/(5))+sin^(-1)(142)/(65sqrt(5))

The value of 3 "tan"^(-1)(1)/(2) + 2 "tan"^(-1)(1)/(5) + "sin"^(-1)(142)/(65sqrt(5)) is :

The value of 3 "tan"^(-1)(1)/(2) + 2 "tan"^(-1)(1)/(5) + "sin"^(-1)(142)/(65sqrt(5)) is :

Value of 3tan^(-1)((1)/(3))+tan^(-1)((1)/(2))+sin^(-1)((1)/(sqrt(5)))+cos^(-1)((2)/(sqrt(5))) is greater than

cos^(-1)((63)/(65))+2tan^(-1)((1)/(5))=sin^(-1)(3/5)

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

tan(sin^(-1)((3)/(5))+cos^(-1)((3)/(sqrt(13)))=

Prove the following: 4tan^(-1)(1)/(5)-tan^(-1)(1)/(70)+tan^(-1)(1)/(99)=(pi)/(4)2tan^(-1)(1)/(5)+sec^(-1)(5sqrt(2))/(7)+2tan^(-1)(1)/(8)=(pi)/(4)

tan^(-1)(1/3)+tan^(-1)(1/5)=(1)/(2)cos^(-1)(33/65)
