In maths what is a tangent and what is a chord?
Tangent:In geometry, the tangent line (or simply the tangent) is a curve at a given point and is the straight line that "just touches" the curve at that point. As it passes through the point where the tangent line and the curve meet the tangent line is "going in the same direction" as the curve, and in this sense it is the best straight-line approximation to the curve at that point.Chord:A chord of a curve is a geometric line segment whose endpoints both lie on the outside of the circle.
What is a slope line?
is it a line that is slanted
What is the set of an equation in two variables in the set of all points in a coordinate plane that represent all the solutions of the equation?
To graph the set of all the solutions to an equation in two variables, means to draw a curve on a plane, such that each solution to the equation is a point on the curve, and each point on the curve is a solution to the equation. The simplest curve is a straight line.
How can you write the equation of the tangent line to the curve?
Well if you have found the derivative (slope of the tangent line) of the curve at that point and you know the xy coordinates for that point in the curve then you set it up in y=mx+b format where y is your y-coordinate, x is your x-coordinate and m is your derivative and solve for b
What do you call the point where a line on a graph changes slope?
Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
What you call the point when a curve changing from concave upward to concave downward?
The point when a curve changes from concave upward to concave downward is called the inflection point. It is the point where the curve transitions from being curved "upwards" to being curved "downwards" or vice versa. At the inflection point, the rate of change of the curve's curvature changes sign.
What is point to point inflation?
Point inflation is the point at which the curve changes its shape with the fixed rate of change. Point to point is the distance between the changes.
What Is Point Of Inflection?
An inflection point is a point on a curve at which the sign of the curvature (i.e., the concavity) changes.
What happens to a point that constantly varies in direction?
A point that constantly varies in direction would trace out a trajectory rather than staying in a fixed position. This trajectory could take many forms depending on the specific variations in direction. It could loop, curve, or move erratically depending on the degree and frequency of the directional changes.
How do you explain that the pencil appears broken in the glass of water?
When light passes from one medium to another (such as from air to water), it changes speed and direction, causing the pencil to appear bent at the point where the light refracts. This is an optical illusion, as the pencil remains unbroken.
How do you find the point of tangency?
A tangent is an object, like a line, which touches a curve. The tangent only touches the curve at one point. That point is called the point of tangency. The tangent does not intersect (pass through) the curve.
What is the decrease in speed?
When speed changes, the rate a which you are going (ex: 22 miles per hour) changes. Direction changes when the direction(ex: north, south, east, west) changes. Any change in speed or direction of motion is known as 'acceleration'.
A six letter word for a plane curve with each point on the curve being and equal distance from a fixed point at the center of the figure?
The distance from the fixed point at the center of a circle to any point on the curve is called the radius.
What is a curve formed by a point which moves according to a mathematically defined rule called?
locus curve
What is a curve on which every point in the same distance from a point called center?
A circle
The point at which a curve intersects a coordinate axis?
It is called an intercept.
What is a line beginning at an end point and extending infinitely in one direction?
The set of points on a straight curve that extends to infinity in both directions is a line. A ray is the set of points that lie on a straight curve that is terminated at a point, and continues to infinity. It is also called a half-line. If the set is terminated at a point at both ends, then it is a line segment.
