The tangent ratio is used for right triangles
Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
Answer:
Quality rotation is the act of a joint moving through a range of motion in a way that is efficient, controlled and repeatable.
