Step-by-step explanation:
Answer:
-0.899
Step-by-step explanation:
In the 4th quadrant, the sine is negative and the cosine is positive. The sine is ...
sin(-arccos(0.437)) ≈ -0.899
_____
You can also use the trig identity ...
sin(x) = -√(1 -cos(x)²) = -√(1 -.190969) = -√.809031 ≈ -0.89946150557
The sine is about -0.899.
Answer:
Step-by-step explanation:
If the extreme ends of a line segment AC are A and C.
If a point B(x, y) divides the segment in the ratio of m : n
Then the coordinates of the point B are,
x =
y =
If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1
Therefore, coordinates of this point will be,
x =
=
=
=
y =
=
=
=
Therefore, coordinates of the point B are .
Factor using difference of cubes, and set each factor equal to 0.
x=(-3+3i\sqrt(3))/(4),(-3-3i\sqrt(3))/(4),(3)/(2)
