Find the value of $ an(θ) $ at $ θ = frac{3π}{4} $ on the unit circle

Answer 1

Abigail Nelson

James Taylor

To find the value of $ \tan(θ) $ at $ θ = \frac{3π}{4} $, we first identify the coordinates on the unit circle:

At $ θ = \frac{3π}{4} $, the coordinates are $ (-\frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2}) $.

So, $ \tan(θ) $ is given by:

$ \tan(θ) = \frac{y}{x} = \frac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}} = -1 $

Therefore, $ \tan(θ) = -1 $.

William King

To find $ an(θ) $ at $ θ = frac{3π}{4} $, note that the coordinates on the unit circle are $ (-frac{sqrt{2}}{2}, frac{sqrt{2}}{2}) $. Thus:

$ an(θ) = frac{y}{x} = frac{frac{sqrt{2}}{2}}{-frac{sqrt{2}}{2}} = -1 $

At $ θ = frac{3π}{4} $, the coordinates are $ (-frac{sqrt{2}}{2}, frac{sqrt{2}}{2}) $. Thus,

$ an(θ) = -1 $
