Question

what are the zeros of a cotangent function? and does amplitude affect cotangent functions?

Answer 1

\[\cot(x)=\frac{\cos(x)}{\sin(x)}\] so zeros of cotangent same as zeros of cosine

Answer 2

that was wrong. sorry

Answer 3

zeros are
\[\frac{\pi}{2}, \frac{3\pi}{2}...\]

Answer 4

so cot theda=o when cos theda=0

Answer 5

yes exactly

Answer 6

odd multiples of pi over 2
\[\frac{(2k-1)\pi}{2}, k \in Z\]
