<h2>Task:</h2>
- Draw a poster that symbolizes-the importance of grammatical signals in developing patterns of idea in communiting to your readers. You will be graded according to the rubrics provided. An example is provided as your guide.
- Using grammatical signals in developing patterns of idea can be like a zipper; because it zips our ideas or combined some informations that we have into one which helps readers understand our message better.
- <u>Grammatical signals</u> are writing devices that serve to maintain text coherence. Short story is one of written medium where we can find these signals.
- <u>Gramatical signals</u> is important because they signal relationship between sentence by means of back reference through the using of pronominal forms, determiners, repetition of key words, ellipsis, parallelism, synonyms and superordination. In short, they signal the relationship between new sentences and the one before it and they are also the important writing devices in text construction.

Answer:
The horse travels 31 feet over an angle of radians
Step-by-step explanation:
- The formula of the length of an arc is L =
× 2πr, where x is the central angle subtended by this arc and r is the radius of the circle
- To change the angle from radian measure to degree measure multiply it by
∵ A carousel horse travels on a circular path
- That means the distance that the horse travels is the length
of an arc of the circular path
∵ The radius of the circular path is 15 feet
∴ r = 15 ft
∵ The horse travel over an angle of radians
- Let us change it to degree by multiply it by
∵ ×
=
= 120°
- use the formula above to find the distance
∵ d = × 2πr
∵ x = 120°
∴ d = × 2π × 15
∴ d = 10π
∴ d = 31.41592654 feet
- Round it to the nearest foot
∴ d = 31 feet
The horse travels 31 feet over an angle of radians
Remark
When you take the limit of
the odd result you get is 1. Later on you will be able to use calculus to show this. For now just take limits of sin(x)/x and make sure you are feeding radians into your calculator.
Now the only question is what is this thing doing?
If a is a constant in
then the result = a.
So that's basically all you need to know to solve your problem.
Series
Each term in the series will be
a*(sin(ax)/x) = a * [sin(ax)/x] * 1 = a * a = a^2
The series will look like this.
1 + 4 + 9 + 16 + 25 + 36 + 49 + 64 + 81 + 100 There is a way of summing this using n notation, but you could just as easily just add the results.
<span>
The formula for this series (if you want a sum) is n*(n+1)*(2n+1) / 6
</span>n = 10
Sum = 10*(11)(21)/6
Sum = 385
Does adding it by hand bring up 385?
