Best ResponseYou've already chosen the best response.3Then find the inverse sine of 0 and and 360 to that answer repeatedly until you have 5 values.

Best ResponseYou've already chosen the best response.3What 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?

Best ResponseYou've already chosen the best response.0i put sin 0 enter and the answer was 0 how do i get 5 values?

Best ResponseYou've already chosen the best response.3Have you ever seen that before?

Best ResponseYou've already chosen the best response.3That is the unit circle. It is called the unit circle because the radius is 1 unit. The sin is like y.

Best ResponseYou've already chosen the best response.3Do you see that the y value is 0 at 0 degrees and 180 degrees?

Mertsj

Best ResponseYou've already chosen the best response.3Your 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?

Best ResponseYou've already chosen the best response.0sorta.. so it would be 0,180,540?

Mertsj

Best ResponseYou've already chosen the best response.30,180,360,540... Just keep adding 180 degrees because every 180 degrees, the y value (which is the sin) is 0.

Best ResponseYou've already chosen the best response.3Or, instead of rotating counterclockwise, we could go clockwise and then the angles would be 180, 360, 540, ...

Best ResponseYou've already chosen the best response.0ohh ok thank you! i have the same question exept its cosine value

Mertsj

Best ResponseYou've already chosen the best response.3Same thing except the cosine is like x.

Best ResponseYou've already chosen the best response.3So where is the cosine 0 on the unit circle?

Mertsj

Best ResponseYou've already chosen the best response.3Look at the picture I drew. For what angles is the x value 0?

Mertsj

Best ResponseYou've already chosen the best response.3How many degrees is that?

Mertsj

Best ResponseYou've already chosen the best response.3And what is the next angle where the x value is 0?

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

Mertsj

Best ResponseYou've already chosen the best response.3yes. so the x value is 0 at 90, 270, 450, 630...

Mertsj

Best ResponseYou've already chosen the best response.3Do you know the definition of tangent?

Mertsj

Best ResponseYou've already chosen the best response.3tangent is equal to sin over cos Have you ever heard that?

Best ResponseYou've already chosen the best response.3\[\tan x=\frac{ \sin x}{\cos x}\]

Best ResponseYou've already chosen the best response.3The only way a fraction can be 0 is for the numerator to be 0. So the tangent is 0 whenever the sin is 0

Best ResponseYou've already chosen the best response.3Are you trying to answer this question: Give 5 angles who tangent is 0?

nikakuz

Best ResponseYou've already chosen the best response.0the question is name five x values for which the tangent function equals to 0

Mertsj

Best ResponseYou've already chosen the best response.3Could you answer this question: Name five x values for which the sine function equals to 0?

Best ResponseYou've already chosen the best response.0yeah we already did that one

Mertsj

Best ResponseYou've already chosen the best response.3So 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"

Best ResponseYou've already chosen the best response.0yeah i read it but i don't understand

Mertsj

Best ResponseYou've already chosen the best response.3The 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.

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

Best ResponseYou've already chosen the best response.3What is the sin of 180 degrees?

Mertsj

Best ResponseYou've already chosen the best response.3What is the cosine of 180 degrees?

Mertsj

Best ResponseYou've already chosen the best response.3\[\tan 180^{o}=\frac{\sin 180^{o}}{\cos 180^{o}}=\frac{0}{1}=0\]
