Question

Use an inverse trigonometric function to write theta as a function of x.

I'll draw...

Answer 1

Is it theta = arctan((x+1)/10)?

Answer 2

yes right \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

tan =opposite/adjacent
