Are you familiar with the unit circle?

Then find the inverse sine of 0 and and 360 to that answer repeatedly until you have 5 values.

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?

Have you ever seen that before?
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
That is the unit circle. It is called the unit circle because the radius is 1 unit. The sin is like y.

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
Do you see that the y value is 0 at 0 degrees and 180 degrees?
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
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?

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
sorta.. so it would be 0,180,540?
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
0,180,360,540... Just keep adding 180 degrees because every 180 degrees, the y value (which is the sin) is 0.

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
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
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
Same thing except the cosine is like x.

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
so it would be 90 180...?

yes. so the x value is 0 at 90, 270, 450, 630...

same but tangent function
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
Do you know the definition of tangent?
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
tangent is equal to sin over cos Have you ever heard that?

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
i think ive heard it

\[\tan x=\frac{ \sin x}{\cos x}\]

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
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

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
ok so then wht

Are you trying to answer this question: Give 5 angles who tangent is 0?
 one year ago

nikakuz Group TitleBest ResponseYou've already chosen the best response.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?
 one year ago

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
yeah we already did that one
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
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"
 one year ago

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
yeah i read it but i don't understand
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
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.

nikakuz Group TitleBest ResponseYou've already chosen the best response.0
so my answer would be exactly the same as the sine one?

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
Let's make sure you understand this.

What is the cosine of 180 degrees?
 one year ago

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
\[\tan 180^{o}=\frac{\sin 180^{o}}{\cos 180^{o}}=\frac{0}{1}=0\]

Mertsj Group TitleBest ResponseYou've already chosen the best response.2
I guess you've gone. Good luck.
