Question

Explain why csc 180 degree is underfined

Answer 1

oh yes okay now \(cosec \theta = \frac{H}{P}\)

Answer 2

Now when \(\theta \rightarrow 180\)

Answer 3

Since sin 180 = 0

csc 180 = 1/ sin 180 = 1/0 1/0 is undefined

Answer 4

You can think now why it's not defined

Answer 5

ah Thanks : )
