Question

please answer my question
If θ is in quadrant 1 and tan θ = 5/12. The value of tan 4θ/5 = ...

Answer 1

does this ask for \(\tan(\frac{4\theta}{5})\)

Answer 2

yeah.. hows the answer? help pls

Answer 3

i have to think, because i don't know of a formula for \(\tan(\frac{ax}{b})\) give me a minute

Answer 4

oh please :)

Answer 5

are you sure this is the exact question:
if \(\tan(\theta)=\frac{5}{12}\) then find \(\tan(\frac{4\theta}{5})\)

Answer 6

this looks like a set up for a \(5-12-13\) right triangle, but i don't see how to use it here

Answer 7

tan(4θ/5) and tan 4θ/5. are there same question? my teacher wrote tan 4θ/5 not tan (4θ/5)

Answer 8

yeah it is the same

Answer 9

the best i can do is whip out a calculator and compute
\[\tan\left(\frac{4\tan^{-1}(\frac{5}{12})}{5}\right)\]

Answer 10

if i answer:
tan [4x(5/12)]/5
thats false?

Answer 11

yes, that is false

Answer 12

how can the ancwer like that? im confuse :(
