Answer:
p:q could be written as in fraction form
<h3>In fraction form
p is the numerator and q is the denominator.</h3>
Step-by-step explanation:
We need to explain, how ratios can be written as a fraction.
We also need explain which part of the ratio is a numerator and which part of the ratio is a denominator.
A ratio is written in the form p : q.
It can be read as p ratio q.
<em>p:q could be written as in fraction form.</em>
Top number in a fraction is a numerator and bottom number in a fraction is a denominator.
<em>In fraction form p is the numerator and q is the denominator.</em>
Example : 2:3 could be written as <em>, where numerator is 2 and denominator is 3.</em>
Sin³ x-sin x=cos ² x
we know that:
sin²x + cos²x=1 ⇒cos²x=1-sin²x
Therefore:
sin³x-sin x=1-sin²x
sin³x+sin²x-sin x-1=0
sin³x=z
z³+z²-z-1=0
we divide by Ruffini method:
1 1 -1 -1
1 1 2 1 z=1
-------------------------------------
1 2 1 0
-1 -1 -1 z=-1
--------------------------------------
1 1 0 z=-1
Therefore; the solutions are z=-1 and z=1
The solutions are:
if z=-1, then
sin x=-1 ⇒x= arcsin -1=π+2kπ (180º+360ºK) K∈Z
if z=1, then
sin x=1 ⇒ x=arcsin 1=π/2 + 2kπ (90º+360ºK) k∈Z
π/2 + 2kπ U π+2Kπ=π/2+kπ k∈Z ≈(90º+180ºK)
Answer: π/2 + Kπ or 90º+180ºK K∈Z
Z=...-3,-2,-1,0,1,2,3,4....
Answer:
√22
Step-by-step explanation:
OK.
-- Since it's the difference of two squares,
the factored form of that expression is
(5x + 12) (5x - 12) .
-- We don't know the value of the expression
until you tell us the value of 'x'. And then, if
'x' changes, the value of the expression also
changes, immediately, without any delay.

Answer:
The value of x is 5.
Step-by-step explanation:
Given that N is the midpoint of OE so we can assume that ON and NE have the same length. In order to find the value of x, we have to do comparison :
