4tan^(-1)(1)/(5)-tan^(-1)(1)/(239)

Prove the following: 4\ tan^(-1)(1/5)-tan^(-1)(1/(239))=pi/4

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

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)

4 tan^(-1)(1/5)-tan^(-1)(1/239) is equal to

4 tan^(-1)(1/5)-tan^(-1)(1/239) is equal o

Find the value of 4"tan"^(-1)1/(5)-"tan"^(-1)1/(239) .

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

Prove: 4 tan^(-1) (1/5 )- tan^(-1)( 1/239) = pi/4

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

Prove that : tan^(-1)((1)/(2))+tan^(-1)((1)/(5))+tan^(-1)((1)/(8))=(pi)/(4)
