Answer:
Taylor series of sin(x) centered at x = 0.
Step-by-step explanation:
Taylor series expansion:

Here, f(x) = sin (x) and a = 0

Putting all the values and expanding, we get,

Solving, we get

For 16 it's 8/10 for 17 it's 52/100 for 18 it's -92/100 for 19 it's -48/100 for 20 it's 86/100 for 21 it's 76/100
The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2
11 hours bc 5 times 11 equals 55
