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.
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 keep reading titanic

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
If you divide the identity cos^2 (x) + sin^2 (x) = 1 by cos^2 (x), you get 1 + tan^2 (x) = sec^2 (x). Thus, the square root of 1 - tan^2 (C) is sec(C).
