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 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.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 only remember useful things. And I consider these useful because I did some low level graphics programmed once and had to use them in practice. Once you understand why these things exist, it becomes that much easier.
