a tangent line is horizontal?
246171
A horizontal tangent line is a mathematical feature on a graph, located where a function's derivative is zero. This is because, by definition, the derivative gives the slope of the tangent line. Horizontal lines have a slope of zero. Therefore, when the derivative is zero, the tangent line is horizontal.

So a diagonal line to the right ( / ) would have a positive slope. A diagonal line to the left ( \ ) would have a negative slope. A vertical line ( | )has an undefined slope and a horizontal line ( ---- ) has a slope of 0.

Those curves that change the alignment or direction are known as horizontal curves, and those that change the slope are vertical curves. As an EA you may have to assist in the design of these curves. ... The straight lines of a road are called tangents because the lines are tangent to the curves used to change direction.

' When the 'rise' is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it. It will look like 'y = something.

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length.

Vertical and horizontal. ... Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system.

Horizontal Lines A horizontal line is a line whose equation is of the form =, where is a real number. All points that lie on the line have a -coordinate of . The slope of any horizontal line is zero, 0. Example: Graph the line =2 and find its slope.

Therefore, tanx has vertical asymptotes at x=(π2)+nπ . No horizontal asymptotes exist for the tangent function, as it increases and decreases without bound between the vertical asymptotes.

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.

Thus, two real tangents to the hyperbola can be drawn from any point only if that point lies outside the hyperbola. If a point lies on a hyperbola, only one tangent can be drawn (basically, coincident tangents) at the same point, while for any point inside the hyperbola, tangents cannot be drawn to the hyperbola.

A tangent line has to be perpendicular to the radius at this point. And perpendicular lines through a given point are unique. Something else holds, if you draw tangents from a point outside of the circle to the circle. Then it is always two tangent lines.

The Horizontal Line Test The x value of a point where a vertical line intersects a function represents the input for that output y value. If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input.

Answer and Explanation: The equation of the horizontal line that passes through the point (2,10) is y = 10.

The x-axis is horizontal (across), while the y-axis is vertical (up-down).

There are an infinite number of lines that are parallel to the x -axis, y=0. All horizontal lines have slope of 0. If lines are parallel then they have the same slope. The slope of a line parallel to the x -axis is 0.

A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line. Horizontal lines do not cross each other.

In a graph, a line parallel to Y-axis is called Vertical Line. It is a straight line which goes from top to bottom. Similarly, the line which goes from left to right and parallel lines to x-axis is called a horizontal line.
