Question

Use a graphing calculator to solve the equation 3 tan 1/3Θ=8 in the interval from 0 to 2pi.

Answer 1

first divide both sides by 3

Answer 2

\[\tan \frac{ 1 }{ 3 } \theta =\frac{ 8 }{ 3 }\]eh?

Answer 3

yep. now take tan^-1 of both sides

Answer 4

\[\frac{ 1 }{ 3 }\theta=1.21\]

Answer 5

yep, now multiply both sides by 3

Answer 6

\(\theta=3.64\)

Answer 7

Wait...is that it? O.o

Answer 8

yep 3.64 rad or 208.3 degrees

Answer 9

ah, okay. Thank you :)
