Tan(–t) = –tan(t) Notice in particular that sine and tangent are odd functions , being symmetric about the origin, while cosine is an even function , being symmetric about the y axis The fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions5/24/21 · Solve the equation $\tan(2x) = 1\tan(x)$ 0 Why is $\tan(\theta)$ the reciprocal of $\tan(90 \theta)$?Tan x、tan^2xの不定積分のやり方を解説。 そしてtan^3xの積分は置換積分を用いて2通りの方法で計算してみます。 算数から高度な数学まで、網羅的に解説したサイト
