Faqs

For data in a table or a graphed line, use the formula for slope m = (y2 – y1) / (x2 – x1). On a graphed line y=mx+by=mx+b, mm is the slope value.

Create a table of values, then use y1∼mx1+by1∼mx1+b for linear regression. Desmos computes the best fit line and displays values for slope mm and intercept bb.

Input your data as two lists and use the formula corr(list1, list2) in Desmos. The calculator instantly gives the correlation coefficient, showing how closely the variables are related.

Desmos can calculate the area under a curve using the integral function. Enter integral(f(x), x, a, b) to compute the area between x=ax=a and x=bx=b.

To make a line, enter a linear equation like y=mx+by=mx+b into the expression box. Adjust mm for slope and bb for y-intercept to position your line.

Enter your data into a table in Desmos, then type an equation like y1∼mx1+by1∼mx1+b for linear regression. Desmos will automatically generate the line of best fit and display parameters for slope and intercept.

Create shapes in Desmos by entering their equations. For a rectangle, use linear inequalities and restrictions. For a triangle, graph three lines and use domain restrictions. Combine parametric, polar, and linear equations for more complex designs.

Calculate standard deviation on Desmos by entering your dataset as a list, such as [4][7][9][12], then use the stdev function—e.g. stdev([4][7][9][12]). Desmos will return the standard deviation value and help visualize the spread on a graph.

To use Desmos Matrix Calculator, select the matrix calculator from the Desmos suite, input your matrix entries, and choose operations like addition, multiplication, inversion, or determinant calculation. The calculator displays results instantly, helping with linear algebra tasks.

Calculate the range on Desmos by graphing your function and checking the highest and lowest y-values on the graph. For exact values, use the restriction feature to limit x-values and watch how the graph changes, revealing the output interval.
