How To Solve For Sigma On A TI83
The TI-83 is a graphing calculator that is used for mathematics; sigma is the Greek letter used in math used to designate summations. With a given function and limit, you can easily enter a summation equation into your TI-83 and solve for sigma. This way you can avoid having to solve the equation by hand and save time.
Step 1
Press and hold the "2nd" button, then press "STAT."
Step 2
Scroll to the right to the "MATH" option, then press "5."
Step 3
Press and hold the "2nd" button then press "STAT."
Step 4
Scroll to the right to select the "OPS" option, then press "5." You will now have "Sum(Seq(" on your screen.
Step 5
Enter the equation to the right of igma, then add a comma. For example, if the equation is 3x+2, then type "3x+2," into the TI-83.
Step 6
Enter the value of x followed by a comma. This is located under the sigma symbol in the equation. For example, if in the equation is says "x=5" then type "5," into the calculator.
Step 7
Enter the value above the Sigma symbol. Follow the value with a comma. If the value in your equation is 7, then you would enter "7,"
Step 8
Enter "1" and finish with "))." If entered properly, your calculator would read something like this: "Sum(Seq(3x+2,X,5,7,1))"
Step 9
Press the "Enter" key to solve for sigma.
