Are you familiar with the unit circle?
no
Then find the inverse sine of 0 and and 360 to that answer repeatedly until you have 5 values.

how?
With your calculator
I don't know how though
inverse sin 0 enter
What in the world are you doing that you don't know anything about the unit circle and don't know how to use your calculator?
i put sin 0 enter and the answer was 0 how do i get 5 values?
trying to learn from an oonline classs

Have you ever seen that before?
yeah
That is the unit circle. It is called the unit circle because the radius is 1 unit. The sin is like y.
Do you see that the y value is 0 at 0 degrees and 180 degrees?
yes
Your problem says to give 5 values for which the sin is 0. There are two of them right there: 0 degrees and 180 degrees. If we would go around the circle another time, we would come to 360 degrees and 180+360 which is 540 degrees. Are you with me?
sorta.. so it would be 0,180,540?
0,180,360,540... Just keep adding 180 degrees because every 180 degrees, the y value (which is the sin) is 0.
Or, instead of rotating counterclockwise, we could go clockwise and then the angles would be -180, -360, -540, ...
ohh ok thank you! i have the same question exept its cosine value
Same thing except the cosine is like x.
So where is the cosine 0 on the unit circle?
um im not sure
Look at the picture I drew. For what angles is the x value 0?
|dw:1375671563924:dw|
How many degrees is that?
90?
Yes.
And what is the next angle where the x value is 0?
so it would be 90 180...?
|dw:1375671659091:dw|
270?
yes. so the x value is 0 at 90, 270, 450, 630...
thank you soo much i just have one more
Or at -90, -270, -450...
same but tangent function
Do you know the definition of tangent?
umm no
tangent is equal to sin over cos Have you ever heard that?
i think ive heard it
\[\tan x=\frac{ \sin x}{\cos x}\]
The only way a fraction can be 0 is for the numerator to be 0. So the tangent is 0 whenever the sin is 0
ok so then wht
Are you trying to answer this question: Give 5 angles who tangent is 0?
the question is name five x values for which the tangent function equals to 0
Could you answer this question: Name five x values for which the sine function equals to 0?
yeah we already did that one
So did you read this post which I made a few moments ago: "The only way a fraction can be 0 is for the numerator to be 0. So the tangent is 0 whenever the sin is 0"
yeah i read it but i don't understand
The sin of 180 degrees is 0. Therefore the tangent of 180 degrees is also 0 The sin of 0 degrees is 0. Therefore the tangent of 0 degrees is also 0 The sin of 360 degrees is 0. Therefore the tangent of 360 degrees is also 0 The sin of 540 degrees is 0. Therefore the tangent of 540 degrees is also 0.
so my answer would be exactly the same as the sine one?
Let's make sure you understand this.
What is the sin of 180 degrees?
0
What is the cosine of 180 degrees?
\[\tan 180^{o}=\frac{\sin 180^{o}}{\cos 180^{o}}=\frac{0}{-1}=0\]
I guess you've gone. Good luck.
yeah i get it thank you soo much!!!!
