For angles that are greater than 90° we define the tangent of θ by tan θ = , unless cos In this case, we say that the tangent ratio is undefined. Between 0° and 360°, this will happen when θ = 90°, or θ = 270°. You will see in the following exercise why this is the case. mongodb for windows 11WebAnd at the same time, I'm going to subtract 20 from both sets.
