Question

3tanx-2cotx=-5
help! (i know to rewrite it in reciprocal ratios but then i get stuck)

Answer 1

ok well you change cotx to 1/tanx so you will get
3tanx -2/tanx = -5
then you multiply the entire equation by tanx so you will get
3tan^2x -2 = -5tanx which will give you a quadratic equation
3tan^2x +5tanx -2 =0
and you should be able to solve from there

Answer 2

thanks! got it :D

Answer 3

your welcome

Answer 4

let me know what you got

Answer 5

i got a pretty weird answer, would x be = 20 degrees 29 minutes, 200 degrees 29 minutes and 109 degrees 32 minutes and 289 degrees and 32 minutes??

Answer 6

o.O before you solved for x what did you get tanx x to be

Answer 7

tanx was 1/3 and -2, then i did the all stations to central thingy for the 4 quadrants

Answer 8

yup yup
well im not sure what minutes are cus i never heard of it with respect to this topic. unless it has something to do with the question
but i got 18.4 degrees 116.6 degrees and 296.6 degrees and well i rounded them off to 1 decimal place

Answer 9

oh right, yeeah it was just tan inverse on the calculator and then theres this button for the minutes conversion

Answer 10

ohhh ok then well i dont know about that. but those are my solutions

Answer 11

cool THANKS ! :D
