Parameterised functions

[disregardthat]

Hi, I have a TI-84 Plus Calculator and wonders wether it is possible to have two more of the parameterised function slots. I need to graph eight functions, but there is a restriction of six.

Do you know of any good ways of solving an equation on the calc? It is long and complex (but real) functions, it will take up to 15 lines on the calc screen, and it has both trigonometric and polynomial form. What I need is an approximation to the first solution of it to three digits. Newton's method won't do, as it will make the iteration function 50 lines long.

Thanks for help

Unfortunately, it is not possible to increase the parameterised function slots on a TI-84 Plus Calculator. However, there are some methods that you can use to solve the equation. One method is to use the Solver application on the calculator, which can solve equations with up to six variables. You can also use numerical integration techniques such as Simpson's Rule or the Trapezoidal Rule to approximate solutions to three digits. Finally, you could also try using a graphing calculator app on your smartphone or tablet, which may have more features available to help you solve the equation.

I can understand your need for additional parameterised function slots on your calculator. Unfortunately, the TI-84 Plus Calculator has a restriction of only six slots. However, there are some workarounds that you can try. One option is to use a graphing software on your computer that allows for more parameterised function slots. Another option is to create a table of values for your functions and plot them manually on your calculator.

In terms of solving your long and complex equation on the calculator, there are a few methods you can try. One option is to use the "solve" function on your calculator, which allows you to enter an equation and solve for a specific variable. Another option is to use the "zero" function, which allows you to find the x-intercept of a function, and then use that value as an approximation for the first solution.

However, if these methods do not give you the desired level of accuracy, you may need to use a more advanced mathematical software or programming language to solve your equation. These programs have the ability to handle longer and more complex equations and provide more precise solutions. I would recommend consulting with a mathematics expert or doing some research on these programs to find the best one for your needs.
