Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = -1 - 3 sin θ

now, recall that, testing for symmetry is done by replacing the argument, and if the resulting function mimics the original function, then the function has symmetry of that type.

so let's test r = -1 - 3sin(θ).

also recall that sin(π) = 0, and cos(π) = -1.

with that in mind, let's check

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
