What is the difference between a linear and quadratic function?
A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
Explain the difference between linear dynamic range with analytical range?
Analytical range refers to the method/procedure used, It can include a non linear response. If you plot the analytical results versus the reference values you will have a linear curve. The linear range could be more precisely given by saying the linear instrument range
What are the characteristics of a normal distribution curve?
Characteristics of a Normal Distribution1) Continuous Random Variable.2) Mound or Bell-shaped curve.3) The normal curve extends indefinitely in both directions, approaching, but never touching, the horizontal axis as it does so.4) Unimodal5) Mean = Median = Mode6) Symmetrical with respect to the meanThat is, 50% of the area (data) under the curve lies to the left ofthe mean and 50% of the area (data) under the curve liesto the right of the mean.7) (a) 68% of the area (data) under the curve is within onestandard deviation of the mean(b) 95% of the area (data) under the curve is within twostandard deviations of the mean(c) 99.7% of the area (data) under the curve is within threestandard deviations of the mean8) The total area under the normal curve is equal to 1.
Why you use semi-log graph over normal graph?
why would you use a semi-logarithmic graph instead of a linear one?what would the curve of the graph actually show?
What is a crest in math terms?
It is a local maximum for a non-linear curve, which may be a periodic curve.
How do you find modulus of elasticity from load displacement curve?
The modulus of elasticity is the slope of the linear portion of the curve (the elastic region).
What is the difference between a linear curve and a parabolic curve?
a linear curve does not represent x^2
Why is product possibility curve linear?
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
What are the examples for exceptional demand curve?
Example of a Linear Demand Curve
What is a linear torque curve?
A torque curve is a plot of torque produced vs RPM, as measured on a dynamometer. It usually is not linear (a straight line).
Linear demand curve diagram?
A Linear Demand Curve Diagram is a diagram that shows how an object or person is shown from youngest to oldest or tallest to shortest
A demand curve with Unitary Elasticity at all points is?
Is negatively sloped linear curve
What is pipe haunch?
Is the top portion or bottom portion of the curve of the pipe.
What is difference between slope and the calculation of elasticity for a linear demand curve?
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
What portion of the volt-ampere characteristics of the diode is linear when is forward biased?
Below the diode's Forward Voltage (Vf) typically 0.7V, the curve is at (roughly) zero. At around 0.5 it begins to curve upward, and at around 0.7V, the voltage drop is almost constant (the curve heads straight upwards to infinity). See link.
As a curve approaches a maximum point the slope will do what?
The slope of the tangent line at the maximum point of the curve is zero. So we say that as a curve point approaches to the maximum point, the slope of the tangent line at that point approaches to zero.
