Question

use a graphing calc to solve the equation 3 tan 1/3 theta = 8 in the interval from 0 to 2pi round your answers to the nearest hundredth

Answer 1

1.21, 4.35 were the answers i got but i want to makes sure i did it right

Answer 2

get a nice graph here

Answer 3

Answer 4

how do i find the answers by looking at this graph though

Answer 5

maybe a better one here, i restricted the domain
http://www.wolframalpha.com/input/?i=3tan%28x%2F3%29%3D8+domain+0+..+2pi

Answer 6

in the picture i sent, look to see where the curve and the line \(y=8\) intersect
that is where they are equal

Answer 7

oh i see i hovered over the red dot and i saw it was 3.63 so after rounding that it would be 3.64 right?

Answer 8

yes, looks good
we could solve it directly if you like, but i think you want to use the graph

Answer 9

if you have to do it in a graphing calculator it is harder, but possible

Answer 10

bro i freaking love you

Answer 11

thanks

Answer 12

lol yw
if you have to use a graphing calculator for a test, do this
graph
\[3\tan(\frac{x}{3})-8\] and then see where it is zero

Answer 13

i.e. where it crosses the \(x\) axis
some graphing calculators will tell you also
