Find the points on the given curve where the tangent line is horizontal or vertical. (Assume 0 ≤ θ ≤ 2π. Enter your answers as a comma-separated list of ordered pairs.) r = 1 − sin(θ)

Tangent line is horizontal at points : and vertical at points : .

Step-by-step explanation:

Given,

where

Let, and . Then,

Now, to find tangent , we have to find,

Therefore,

The numerator of is 0 implies the tangent line is horizontal. That is,

or,

or,

Now, implies that there exist a vertical tangent at .

And the denominator of is 0 implies the tangent line is vertical. That is,

When,

Hence, tangent line is,

horizontal at points :

vertical at points :
