Answer:
Sine is an odd function and presents positive values in the 1st and 2nd quadrants and negative values in the 3rd and 4th quadrants.
Step-by-step explanation:
-sin(x) = sin(-x)
This property is valid because the sine trigonometric function presents positive values in the first two quadrants and negative values in the third and fourth quadrants. The sine function is an odd function with symmetry with respect to the origin, which means that sin(x) and sin(-x) will always present opposite signs.
B.66 I am positively absolutely sure. Hope this helps!
About 379.1666666666666
The 6 is repeating. Or about 379 if your rounding.
Answer:
.
Step-by-step explanation:
We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is 
we get;
Now we will take the common factor from the last 2 terms which is 3 we get;
Here we get 2 terms in which 
is common factor.
Hence After factorizing the given equation we get .
