Solve the equation 3tan(2x+15)=4 for 0

Question

Solve the equation 3tan(2x+15)=4 for 0<x<180

anonymous · Answer

3tan(2x+15)=4
tan(2x+15)=4/3
2x+15=arctan(4/3)
2x =arctan(4/3)-15
x =(arctan(4/3)-15)/2

anonymous · Answer

Pick the value that is between 0 and 180

anonymous · Answer

Is that the only value?

anonymous · Answer

There are multiple values because the equation is  ______
I forgot the word but when you graph a cos and sin you just see it go on and on and on. So you can have multiple values for x but they want you to find it for a very specific spot between 0 and 180

Usually they ask you in terms of pi
it should be between 0 and pi
And the word is periodic and the period is between 0 and 2pi
