Without resorting to L'Hopitâl's rule,
With the rule, we get the same result:
Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:
Taking as , is equal to
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
You should be able to set up a proportion between the sides something like (18+x)/x=(56+21)/56
Answer:
The number after - 2 is - 3.5.
Step-by-step explanation:
Follow the pattern
Let the number be after -2
as in the question after 4 we have 2.5 then 1 and so on.
if we subtract 4 from 2.5 we get
2.5 - 4 = -1.5
similarly: 1 - 2.5 = -1.5
-0.5 - 1 = -1.5
and now
x -(-2) = - 1.5
x = - 1.5 -2
x = - 3.5
so the number after - 2 is - 3.5.
