You know that for any , neither sin nor cos can be greater than 1. how can you explain this using the unit circle definitions of
Feliz [49]
In the unit circle the hypotenuse of the triangle formed  is equal to radius of circle , which = 1. The point on the circle formed by the intersection of the hypotenuse  is  (cos q , sin q)  where q is the angle between the x axis and the hypotenuse.   As the hypotenuse = 1 the opposite and adjacent sides of the triangle < 1   so sin and cos of q  must both be  <= 1.

Find the length of a segment with an endpoint of (2, 1) and a midpoint of (–2, –1).
Travka [436]

Answer:

Length of segment =4\sqrt5 units = 8.94 units

Step-by-step explanation:

Given:

End point of line: (2,1)

Midpoint of line: (-2,-1)

To find length of line segment.

Solution:

Distance from endpoint to midpoint is half the length of segment as the midpoint divides the line into equal halves.

Distance from end point to mid point can be found out using distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2)

Plugging in points for end point (2,1) and midpoint(-2,-1).

d=\sqrt{(-2-2)^2+(-1-1)^2)

d=\sqrt{(-4)^2+(-2)^2)

d=\sqrt{16+4)

d=\sqrt{20}

d=2\sqrt{5}

Length of half segment =2\sqrt{5} units

∴ Length of segment = 2\times length\ of\ half\ segment= 2\times 2\sqrt5=4\sqrt5 units
