The quickest way to get the series is if you already know the series for sine:
Then just multiply the series by 
to get
The first four nonzero terms are simply the first four terms:
If it's just simplifying the equation then the answer is:
-4.338
Length - 7/8 miles
Area - 8/20 miles
We know from the equation that Area = Length x Width.
We need to rearrange so that Width = Area ÷ Length
Width = 8/20 ÷ 7/8
= 8/20 x 8/7
= 16/35
Therefore, the width will be 16/35 miles.
Answer:
√3
Step-by-step explanation:

Racionalización de denominadores 3 / v3 tres sobre raíz cuadrada de 3
da
Usando el método de índices
3 / √3 = 3¹ / 3¹ / ²
= 3¹ / 3⁰.⁵
= 3¹⁻¹ / ²
= 3 ¹ / ²
= √3
Esto también se puede resolver multiplicando tanto el numerador como el denominador por √3
3 / √3 * √3 / √3
= 3√3 / √3 * 3
= 3√3 / √9
= 3√3 / 3
Los tres se cancelan y nos queda √3

Rationalization of denominators 3 /v3 three over square root of 3
gives
Using the method of indices
3 / √3 = 3¹/ 3¹/²
= 3¹/ 3⁰.⁵
= 3¹⁻¹/²
=3 ¹/²
=√3
This can also be solved multiplying both the numerator and the denominator by √3
3 / √3 * √3/√3
= 3√3/ √3*3
= 3√3/ √9
= 3√3/ 3
The three are cancelled and we are left with √3
