SUMMARY

The discussion confirms that secant is indeed inversely proportional to cosine, as defined by the equation \sec(\theta) = \frac{1}{\cos(\theta)}. The user calculates secant using the values cos = 5/5.38, leading to the conclusion that secant equals 5.38/5. This relationship is fundamental in trigonometry, establishing the direct connection between these two functions.

PREREQUISITES
  • Understanding of trigonometric functions, specifically cosine and secant.
  • Familiarity with the unit circle and angle measures in radians or degrees.

cos = 5/5.38

so

secant is = 5.38/5?

thats my solution anyway, just want to check if i got it right.
