" काजिए कि "tan^(-1)(1)/(5)-lon^(-1)(1)/(70)+lan^(-1)(1)/(99)=(pi)/(4)

4tan^(-1)((1)/(5))=tan^(-1)((1)/(70))+tan^(-1)((1)/(99))+(pi )/(4)

4tan^(-1)((1)/(5))-tan^(-1)((1)/(70))+tan^(-1)((1)/(99))=pi/4

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)

4tan^(- 1)(1/5)=tan^(- 1)(1/70)-tan^(- 1)(1/99)+pi/4

4tan^(- 1)(1/5)=tan^(- 1)(1/70)+tan^(- 1)(1/99)+pi/4

Find the value of 4 tan^(-1).(1)/(5) - tan^(-1).(1)/(70) + tan^(-1).(1)/(99)
