At what values of x does the graph of f(x)= sin x intersect the x-axis?
a) all multiples of pi/2
b) odd multiples of pi/2
c) all multiples of pi
d) even multiples of pi

c) all multiples of

Step-by-step explanation:

The given function is

The graph of this function is shown in the attachment.

We can see that the graph intersect the x-axis at

We can also solve the equation,

and obtain;

, where n is an integer.

as the x-values where the graph intersect the x-axis.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
