Is there any relation between gradience and gradient?

Gradience of a scalar point function can be taken but we take gradient of a line.I was wondering if there is any connection between them.Is there?Is there any relation between gradience and gradient?
Gradience is gradient squared devided by pie

  • How do you calculate the maximum gradient of an unknown curve?

    I have a single data variable that varies with time. It is actually a pressure trace for a cylinder and increases to a peak over time then decreases. I want to find the the maximum pressure rise rate or maximum gradient of the curve. The curve has no equation and is just a set of time varying data points.





    Is there a method for estimating the maximum gradient from the data?How do you calculate the maximum gradient of an unknown curve?
    Well. You can keep drawing tangents until one which you find is the steepest. From your info, i have the idea that the curve is in the shape of a bell. So perhaps you can try drawing tangents at the mid-range of the curve.





    Hope this helps=)

    How do i work out the gradient ?

    i need to work out the gradient of a line with the coordinates 2,1 and 5,3. i have to work it out by just using the coordinates given and i am not allowed to just count the sqaures. Please could you give me some instructions on how to work out the gradient by just knowing the coordinates.How do i work out the gradient ?
    The gradient is the change in the x coordinate divided by the change in the y coordinate.





    So your x coordinates are 2 and 5,


    the change in the x coordinate is


    5 - 2 = 3





    y coordinates are 1 and 3


    the change in the y coordinate is


    3 - 1 = 2





    So the gradient is


    3/2 = 1.5





    Hope that helps :)How do i work out the gradient ?
    Gradient = (difference in y)/(difference in x)


    = (3-1)/(5-2) = 2/3
    gradient


    = (3 - 1)/(5 - 2)


    = 2/3
    Its (3-1)/(5-2) = 2/3.

    How will Cyanide affect the H+ gradient? How will it affect the production of ATP?

    (Cyanide is a poison that prevents the transfer of electrons from the electron carriers to oxygen)How will Cyanide affect the H+ gradient? How will it affect the production of ATP?
    Cyanide 鈥?cyanide will inhibit the electron transport chain, preventing


    electrons from reaching O2 and preventing protons from being pumped out,


    thus preventing ATP synthesis. If electrons can鈥檛 be disposed of, then


    NADH will not be reoxidized and glycolysis will initially be inhibited, unless


    it can carry out fermentation to meet its energy needs. Then glucose


    breakdown will increase to supply those needs with a less efficient pathway.

    How do I convert a gradient to degrees?

    Hello...





    I am curious as to how I convert a gradient (in the form 1:10) into degrees.





    For example, if a road is to have a slope of 1:10, then how to I convert this into degrees?





    Thanks for all answersHow do I convert a gradient to degrees?
    On the roads, the gradient or grade is the vertical rise divided by the horizontal run. So the angle from the horizontal is the arctangent of the (rise divided by the run).


    For trains, the gradient is the verical rise divided by the length of the slope, so the angle from the horizontal is the arcsin of the (rise divided by the slope).


    For small angles, the difference is negligible.How do I convert a gradient to degrees?
    Very simple: The gradient given in the form a:b means simply that the RATIO of the vertical component to the horizontal component is a: b or a/b. Therefore, the tangent of the angle made by this slope to the horizontal is also given by the ration a/b. To find the angle in degrees, all you have to do is read the value arc(tan) of a/b or in your example 1/10 = 0.1


    which gives an angle of 5.71 deg
    Simply find the arctangent (inverse tangent) of the ratio. E.g. for your question, find arctan(1/10). This is written as tan^-1 on your calculator.
    A gradient of 1 : 10 means that as you travel 10 units along the road you rise 1 unit vertically. From basic trigonometry, this means that sin(a) = 1/10 where a is the angle to the horizontal.





    So to convert gradient g to degrees





    a = arcsin(1/g)





    (you can use any scientific calculator, where arcsin may be called inv sin or sin^-1).
    Sorry Rabbit, Freddie is definitely right, its inverse tangent

    How to calculate the Hydraulic gradient (i) in a school laboratory?

    In order to measure the hydraulic conductivity of water I need to calculate the Hydraulic gradient (i), but dunno how. I know the formula i = 螖H / l, but what is H, I, and how to measure them in a school laboratory?





    Please help me ASAP!! thanks!How to calculate the Hydraulic gradient (i) in a school laboratory?
    Cheat off the paper of the nearest egg-head, silly. That's how I did it.

    An ';egg-head'; is a smart nerd. The cheat part should be easy to understand.

    How does a river's gradient affect its ability to erode land?

    gradient= slant, degree of inclination. please give some sources, :).How does a river's gradient affect its ability to erode land?
    The higher the gradient, the faster the movement of water, the more the erosion ; Direct relationships.

    Gradient


    The gradient of a stream is a critical factor in determining its character, and is entirely determined by its base level of erosion. The base level of erosion is the point at which the stream either enters the ocean, a lake or pond, or enters a stretch in which it has a much lower gradient, and may be specifically applied to any particular stretch of a stream.


    In geologic terms, the stream will erode down through its bed to achieve the base level of erosion throughout its course. If this base level is low, then the stream will rapidly cut through underlying strata and have a steep gradient, and if the base level is relatively high, then the stream will form a flood plain and meanders.
