Converting Radians to Surds: A Helpful Table for Complex Number Calculations?

Click For Summary
SUMMARY

This discussion focuses on the need for a reference table that converts radians to surds, specifically for trigonometric functions. The user mentions examples such as tan-1(-1) equating to -π/4 and cos(-π/6) resulting in √3/2. A recommended resource is provided, which is the SOS Math trigonometric table. Additionally, a suggestion is made to perform a Google search for "Trigonometry tables" to find more comprehensive data.

PREREQUISITES
  • Understanding of trigonometric functions such as tangent and cosine
  • Familiarity with radians and their conversion to surds
  • Basic knowledge of inverse trigonometric functions
  • Ability to navigate online educational resources
NEXT STEPS
  • Research "trigonometric identities and their proofs"
  • Explore "inverse trigonometric functions and their applications"
  • Study "how to convert between radians and degrees"
  • Investigate "trigonometric tables and their uses in calculations"
USEFUL FOR

Students, educators, and anyone involved in mathematics or engineering who requires a deeper understanding of trigonometric functions and their conversions.

Hi There,

Can someone please tell me where I can find a table/ data that converts radians to surds. I don't know what to call it but, for instance to tan^-1(-1) = -Pi/4 and, cos(-pi/6) = root3/2 ?

Thank you :)
