1) Click on button on the menu bar 2) Write your desired formula/equation and click insert OR 2) Click on the left bottom button (above the insert button) and write your desired formula/equation from preexisting formulas/equations (on the menu bar) How toUse a Table of Values to Graph the Equation y=x2 y = x − 2 y = x 2 Substitute −2 2 for x x and find the result for y y y = (−2)−2 y = ( 2) 2 Solve the equation for y y Tap for more steps Remove parentheses y = ( − 2) − 2 y = ( 2) 2 Subtract 2 2 from − 2 2In particular, y = cos x is periodic with period 2π This means that if the point (x, y) lies on the graph, then the point (x2kπ, y) will also lie on the graph where k is any integer For example, (x 2π, y) and (x − 2π, y) will both lie on the graph Graphing y = sin x
