sin(0) = 0 but, in general, the sine graph need not start at 0.

For example, sin(x + 2) does not start at 0.

What type of line is always found on a graph of constant speed?

it depends on what the graph is. if it is a distance vs time graph, the line will be a line with the slope being the speed/total time if it is a speed vs. time graph, the line will be horizontal at y=the speed if it is an acceleration vs time graph, the line will be horizontal at y=0


How are the discriminant and the graph of a quadratic equation related?

If the discriminant = 0 then the graph touches the x axis at one point If the discriminant > 0 then the graph touches the x axis at two ponits If the discriminant < 0 then the graph does not meet the x axis


What is the sine of 180?

The sine of 180 degrees is 0. Remember, the sine value on a unit circle is the y-value. If you find f(pi) in the function f(x)=sin(x), you will get zero as an answer.


How does the y-intercept of the line y x-3 affect the graph?

the y intercept is -3 so the y axis at (0,-3) hope that helps and the slop is 1 so the graph will start at (0,-3) and go up one and to the right one and keep going


Why Sine and Cosine are always less then 1?

That is not correct: they are always LESS-THAN-OR-EQUAL to 1. They are also always greater-or-equal to minus 1.The fact that this is so follows directly from the definition. Two different definitions are commonly used:1) The sine is the y-coordinate of a unit circle (a circle of radius 1, with center at coordinates (0, 0)). The cosine is the x-coordinate of the same circle. The highest point on the circle has the y-coordinate 1 (at 90 degrees).2) In a right triangle, the sine is the side opposite to the angle considered, divided by the hypothenuse. The hypothenuse is of course longer than the other sides (except in the extreme case of 0 or 90 degree angles - this would not be properly called a triangle).

What is the difference between a sine graph and a cosine graph?

Oh, dude, it's like asking the difference between a hot dog and a hamburger. So, like, the main difference is just a phase shift of 90 degrees. Sine starts at zero, cos starts at one, but they're basically like two sides of the same math coin.


How does the graph of the cosine function differ from a graph of a sine function?

the graph of cos(x)=1 when x=0the graph of sin(x)=0 when x=0.But that only tells part of the story. The two graphs are out of sync by pi/2 radians (or 90°; also referred to as 1/4 wavelength or 1/4 cycle). One cycle is 2*pi radians (the distance for the graph to get back where it started and repeat itself.The cosine graph is 'ahead' (leads) of the sine graph by 1/4 cycle. Or you can say that the sine graph lags the cosine graph by 1/4 cycle.


What do you do on your line graph if you don't want to start on 0?

start on the letter a.


What is the value of the sin?

If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.


What is the sine of 0?

Sine (0) = 0 Sin(30) = 0.5 Sin(45) = 0.7071... Sin(60) = 0.8660.... Sin(90) = 1 Are just a few of the Sine(Trigonometric) values.


Do graphs have to start at the number zero?

yes a graph has to start from a point 0.


What is sine 0?

zero


When might you want to use a scale or graph that doesnt start at 0?

when you have a chart or graph that starts at a very high number in which case, there is a symbol for that.


Is the sine of an angle positive?

The sine of an angle between 0 and 180 degrees is positive. The sine of an angle between 180 degrees and 360 degrees is negative. At 0, 180 and 360 degrees the sine is 0.The sine is a periodic function with period 360 degrees, so angles differing by a multitude of 360 degrees have the same sine. Hence, for instance, the sines of the angles 0, 360, 720, ... are equal, namely 0.In any right triangle the sine of one of the non-right angles will be positive, since these are greater than 0 and less than 90 degrees.


Is the sine of an acute angle is greater that 1?

No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.


What does 0 mean in a graph?

It is the point of origin of the x and y axes of the graph


How do you find the the sine of -900 degrees?

Divide -900 by 360, and the remainder will be the angle you need to find the sine of: -900 / 360 = -2.5 --> -900 = 360*(-2 - 0.5), so sine(-180°) = sine(-900°). sine(-180°) = 0
