Answer:

C

Step-by-step explanation:

Using sum/difference to product identity

• sin x - sin y = 2 cos(\frac{x+y}{2}) sin (\frac{x-y}{2})

with x = 4Θ and y = 2Θ

Then

sin(4Θ) - sin(2Θ)

= 2 cos(\frac{4o+2o}{2}) sin(\frac{4o-2o}{2})

= 2cos(3Θ)sinΘ → C

Fiesta28 [93]

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right
