That would be
cos x
sin x + cos x * --------
sin x

sin x
Mult sin x by ----------
sin x

to obtain

(sin x)^2
------------
sin x

and then add

(cos x)^2
-------------
sin x

with the outcome being

(sin x)^2 + (cos x)^2 1
--------------------------- = --------- = cos x (answer)
sin x sin x

Help find the distance between two points?

miv72 [106K]

Answer:

4

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = ( $\frac{\sqrt{6} }{2}$ , $\frac{\sqrt{58} }{2}$ )

AB = $\sqrt{((\frac{\sqrt{6} }{2})^2 }$ + $\{(\frac{\sqrt{58} }{2})^2 }$

= $\sqrt{\frac{6}{4} }$ + $\frac{58}{4}$

= $\sqrt{\frac{64}{4} }$

= $\sqrt{16}$

= 4
