Finding the x and y intercepts

[vane92]

f(x)=sin(x)/(1+cos(x))
So I set it equal to zero to find the y-intercept
sin(x)=0(1+cos(x))
x= 0,∏ so the y-int: (0,0) and (0,∏)

To find the x intercept I would substitute 0 for x so,
sin(0)/(1+cos(0))=y
0/1+1=y
y=0 so the x-int: (0,0)

would that be right?

Unfortunately, there are a few mistakes. Firstly, you are confusing the x and y-axis a bit. To find the y-intercept you would set x=0 (the y-axis has equation x=0) and vice versa. Secondly, you listed the points (0,0) and (0,π). You can not have two points on a function with the same x-value. It violates the definition of a function. Surely you meant the points (0,0) and (π,0). Finally, you incorrectly solved the equation {\frac{\sin x }{1+cos x}}=0

Not only is it necessary for sin x to be zero, but 1+ cos x must also be nonzero. x = \pi does not fulfill this second requirement.
