To draw a circle in Desmos Graphing Calculator, enter the equation: (x – h)^2 + (y – k)^2 = r^2 Example:(x – 2)^2 + (y + 3)^2 = 16 This will create a circle centered at (2, -3) with a radius of 4.
Type sqrt(x) to graph the square root function. For other roots, use fractional exponents, such as x⅓ for a cube root.
Type a number or variable followed by the caret symbol ^ and the exponent. For example, x^3 lets you graph x³.
Use braces to add domain restrictions, e.g., y = x^2 {0 < x < 5} only graphs for xx between 0 and 5.
Click the “+” button and select “Table.” Input your xx and yy values in the columns and see the data graph instantly.
Enter variables with subscripts by typing the underscore symbol. Example: a_1 creates a1a1 automatically.
In Desmos, use log_b(x) to create a logarithm with any base bb. For example, log_2(8) calculates base-2 logarithm of 8.
