Answer:
The approximate value of 
is 1.366.
Step-by-step explanation:
Let , we proceed to simplify the formula until a form based exclusively in sines and cosines is found. From Trigonometry, we shall use the following identities:
(1)
(2)
(3)
Then, we simplify the given formula:
If we know that 
, then the approximate value of the given function is:
Answer:
21 + 25i√3
Step-by-step explanation:
⇒ equation: (p√−3)+q
⇒ p = 25
⇒ q = 21
<em>Plug in:</em>
((25)√−3) + 21
√−3 = i√3
25i√3 + 21
Answer:
7.722cm^2, x=129
Step-by-step explanation:
12*12=144- area of the whole square
the diameter for the circle is 12
radius is 6
Area for circle= pi* r²
3.142*6^2=113.112
144-113.112=30.888
30.888/4=7.722
