Wie finden Sie die genauen Werte von cot, csc und sec für 180-Grade?

$cot 180 = cot π = \frac{1}{tan π} = \frac{1}{0} = \infty$ $cot 180 = cot pi = 1/ tan pi = 1 / 0 = oo$

$csc 180 = csc π = \frac{1}{sin π} = \frac{1}{0} = \infty$ $csc 180 = csc pi = 1 / sin pi = 1 / 0 = oo$

$sec 180 = sec π = \frac{1}{cos π} = \frac{1}{- 1} = - 1$ $sec 180 = sec pi = 1 / cos pi = 1 / -1 = -1$

Finden $cot 180, csc 180, sec 180$ $cot 180, csc 180, sec 180$
