The hoodie says🔽
"I'm sqrt(1 tan²(c)) and I know it."
Let me solve it🤓
In trigonometry, there is an identity:
1 tan²(c) = sec²(c)
Taking the square root of both sides gives:
sqrt(1 tan²(c)) = sec(c)
So the expression on the hoodie simplifies to "sec(c)".
When spoken aloud, "sec(c)" sounds like "sexy".
Therefore, the hoodie actually reads:
"I'm sexy and I know it."
A clever math pun. Those who are familiar with trigonometry will get it. Cute tho😉
1 tan(c)^2 = sec(c)^2
and
sqrt(1 tan(c)^2) = sec(c)
