Trigo-nom-etry

If someone didn't learn enough trigonometry in school:

1+tan²c = cos²c/cos²c + sin²c/cos²c = (cos²c + sin²c)/cos²c = 1/cos²c;

sqrt(1/cos²c) = |sec c|

And here is for the people who still don't get the joke

The reading of the answer is very similar to the word "sexy", which makes the whole sentence a reference to the song "Sexy and I Know It" by LMFAO.
- Thanks for this! While I absolutely love science, math is why I never pursued it.
  
  That and I'm waaaaayyyyyyyyyyyyy too stupid. Lol
- But I was taught that the proof was in the pudding
- Thank you for this. Trig was definitely the hardest of the maths for me.
  
  I never learned it. This is one of the few times in my life where it would've been useful
- I was in advanced math classes from like 4th grade all the way up to AP Calc 2 my junior year. Aced all of them except trig. I just could not wrap my head around it.
  
  Trig isn't that bad? It's just about relationships between angles and triangles/circles. If you learn SOH CAH TOA and what the inverses are/mean you've pretty much got it.
- I learned it but promptly forgot it. Thanks.
- Only really needed the right ratio of trig and this song: https://m.youtube.com/watch?v=wyx6JDQCslE
I, a smart person, totally get the joke. But could you explain it to my friend?
- Here’s a hint
  
  oh yes! this is really helpful to me
  
  but my dummy friend still don't get it
  
  I showed that to my friend, and I still don't think they got it.
- you also have a dumb friend I see?
I keep reading titanic
Hardy har har
The first thing I thought was "that's not the formula for secant" and it's not. I checked.
- It rearranges to secant of c
- Permanently Deleted
