Solve for x - tan^-1 (x+1) + tan^-1 (x-1) = tan^-1 8/31 Share with your friends Share 10 Neelima Sreekumar answered this LOL - lizil -5 View Full Answer Neelima Sreekumar answered this Yeah I'm pretty sure she appreciates my answer :)) -11 Apurva answered this Apply tan to both sides: tan [tan^-1 (x+1) +tan^-1 (x-1)] = tan(tan^-1 8/31) [(x+1) + (x-1)] / [1- (x+1)(x-1)] = 8/31 by using tan(a+b) formula. ==> 2x/ (2 - x^2) = 8/31.==>16 - 8x^2 = 62x==> 4x^2 + 31x - 8 = 0==> (4x - 1)(x + 8) = 0.==> x = 1/4 or -8. 66 Yash Verma answered this i agree with the Apurva -5 Yash Solanki answered this X=1/4 is only possible solution 13 Champ answered this F**k -18 D answered this Only 1/4 be the possible solution for this equation -4 Deeksha answered this Here's the easiest ans 16 Yash Agrawal answered this YO -2 Ankur Singh Rajpoot answered this Tan inverse( X + 1) + tan inverse(x - 1)= tan inverse 8 /31 16 Sushant answered this Solution -2 +918xxxxxx85 answered this Solve the equation -1
