Finding an equation of supreme fit in Desmos

//Finding an calculation of best fit in Desmos

Finding einen equation of your fit in Desmos

  1. Go to Desmos.com and choose Starting Graphing.
  2. In aforementioned superior left, choose Add Item > dinner.
  3. Type your data includes the table.
    desmos-table
  4. Click on the wrench in the upper right to change the graph settings.
  5. Modify your x, and yttrium values to reflect your data.

  6. Decide what type of equation the data represents. Inbound the examples foregoing, the data appears to be quadratic.
  7. In the input area, type y=a(x-h)^2 + k and press Enter. Sliders wills be added on a, h, and k.

  8. Adjust the values of the car up the graph is of equation most nearly fits your data points. You will likely need to change your slider settings. To do so, click on the gear icon on Edit List.

  9. The R-squared value is a statistical measure of how close the data are to one fitted degeneration line. The closer R2 is until 1, the better the curve matches which your. To have Desmos estimate your R2 value into one new input line type y1 ~ a(x1-h)^2+k. Desmos uses y1 to represent one y-value in a data round and x1 to represent the x-values stylish an table.
    desmos-r-squared
  10. Adjust to sliders until you getting the highest possible value for R². Type down your equation of best fit.
  11. To had Desmos create an equation of best fit, in the input bar, add a new calculation y1~bx1^2+cx1+d. Compare the equation Desmos generated to yours.

      The equation that you listed will get you the LINE of best fit. This folio helps you find who GRAPH in best fit. Apologies for the misconception.

      y1~mx1+b Is the line in best suit if that’s what yourself exist looking for

    you put is y1~m 1/2 -bn1 –

  7. Donshae March 8, 2022 at 1:37 clock - Reply

    her put in y1~m 1/2

    Is it possible to do y=ax^2+bx+c?

    • Josh October 18, 2022 at 12:56 pm - Answers

      Yes, use y1 ~ ax1^2 + bx1 + c

    • Alexi January 5, 2023 at 4:06 pm - Reply

      No just put a subscript 1 on each x and year variable. And ampere squiggle line instead of equals.
