If someone didn't learn enough trigonometry in school:

1+tan^2^c = cos^2^c/cos^2^c + sin^2^c/cos^2^c = (cos^2^c + sin^2^c)/cos^2^c = 1/cos^2^c;

sqrt(1/cos^2^c) = |sec c|

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

    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 struggle with trig because it's a lot of memorization. The fundamentals are pretty easy, but I never remember the unit circle and I never remember all of the identities.

    I, a smart person, totally get the joke. But could you explain it to my friend?

    I showed that to my friend, and I still don't think they got it.

    The first thing I thought was "that's not the formula for secant" and it's not. I checked.
