Answer:
The Population Density is 
.
Step-by-step explanation:
Given,
Total number of People = 900,000
Total Land Area = 1800 sq. mi.
Solution,
For calculating the population density, we have to divide the total number of people by the area of the land.
This can be framed in equation form'
Now putting the given values, we get;
Hence The Population Density is .
Sin² x + sin x cos x = 0
sin x ( sin x + cos x ) = 0
sin x = 0 ; x 1 = k π ; k ∈ Z
sin x + cos x = 0 / ²
sin² x + 2 sin x cos x + cos² x = 0
2 sin x cos x + 1 =0
sin ( 2 x ) = - 1
x = 3π / 2 + 2 kπ / : 2
x 2 = 3π / 4 + kπ ; k ∈ Z
We know that:
limx→0
sin(x)/x
= 1.
and
cscx = 1/sinx
so,
<span>limx→0 x/sinx = 1</span>
