Why is a slope of a horizontal line zero?
The slope of a line is the tangent of the angle made by the line with the X-axis. Since for a horizontal line, this angle is 0 and tan(0) = zero, the slope of a horizontal line is zero.
Why is the slope of a horizontal line zero?
The slope of a line is the tangent of the angle made by the line with the X-axis. Since for a horizontal line, this angle is 0 and tan(0) = zero, the slope of a horizontal line is zero.
What is the symbol for an angle?
Usually the Greek letter theta is used. It looks like a 0 (zero) with a horizontal line through it.
Why does the equator represent zero degrees latitude?
I believe it dates back to when the North Star was used to find latitude by ancient sailors. Degrees latitude was found by the angle between the North Star and the horizon. Since the North Star sits on the horizon at the equator the angle is zero therefore latitude is zero degrees.
What is the equation of a line with a slope of zero?
A horizontal line has a slope of zero. The equation of a horizontal line is y = a.
What does a zero angle look like?
A zero angle is a straight positive line. The x coordinate is positive and y is zero. In addition, zero angle is a coterminal of 360 degree angle meaning that they lie in the same position.zero angle.------------------>An angle whose measure is 0 degrees is called zero angle.
When can a nonzero vector have a zero horizontal component?
When the direction of the vector is vertical. Gravitational force has zero horizontal component.
What is the reference line when determining the latitude?
The equator is zero latitude.
Slope of horizontal line?
The slope of a horizontal line is zero.
What is a zero slope?
A horizontal line.
What is a whole circle bearings?
Whole circle bearing is the angle to a given point taking north as zero degrees
What is the optimun angle of declination?
Zero degrees! If the angle of declination is 0°, then magnetic north is exactly the same as true north, making it much easier to navigate. But really, there isn't any "optimum" angle. One angle is just as good as another as long as you know how to correct for it in the right way.
