SUMMARY

The solution to the equation tan(theta) = 2/5 is approximately 2.62 radians. To arrive at this result, one must use the arctangent function, specifically arctan(2/5). It is crucial to ensure that the calculator is set to the correct mode, either degrees or radians, to obtain the desired output. This discussion highlights the importance of understanding trigonometric functions in the context of complex numbers.

PREREQUISITES
  • Understanding of trigonometric functions, specifically tangent and arctangent.
  • Familiarity with radians and degrees in angle measurement.
  • Basic knowledge of complex numbers and their trigonometric forms.
  • Ability to use scientific calculators or software for trigonometric calculations.
NEXT STEPS
  • Learn how to use the arctangent function on various calculators.
  • Study the relationship between radians and degrees in trigonometry.
  • Explore the trigonometric forms of complex numbers in more depth.
  • Practice solving additional trigonometric equations using different values.
USEFUL FOR

Students studying trigonometry, particularly those working with complex numbers, as well as anyone needing to solve trigonometric equations using calculators.

The Attempt at a Solution


I forgot how, I had no clue so I looked in the solutions and it was 2.62 radians, I just don't know how they got that, I am not sure on what to do. Its for trigonometric forms of complex numbers.


Thanks for any help!

You don't have a calculator or something?
Usually that's the way to solve a problem like this, unless you want to iterate it...
 
Whats do i type in? A friend told me to do the arctan of 2/5 but that just gives me some decimal.
 
Is your calculator in DEG? if not, then put it in RAD
