Question

tan(arctanx + arctan 1/4)=7/11, find x

Answer 1

You should get the inverse of it

Answer 2

trololololol

Answer 3

hahahaha!

Answer 4

i already did that and i just want to make sure that my answer is correct :))

Answer 5

nakita nga lang kita eh

Answer 6

ang susungit naman ng mga tao dito

Answer 7

kala mo lang un.. may mabait dito :))

Answer 8

just use tan double angle formula.....

Answer 9

arctanA + arctan B = arctan((A+B)/(1-AB))

Answer 10

wait.. i'm confused @_@

Answer 11

i'm confused too

Answer 12

mee too

Answer 13

arctanx + arctan 1/4 = arctan((x+1/4)/(1-x/4))
tan(arctanx + arctan 1/4) = (x+1/4)/(1-x/4) =7/11

Answer 14

now can u find x ?
(x+1/4)/(1-x/4) =7/11
