hi, i'm new and i buy recently a ti nspire cas. I used a ti 89 and when i used the ti 89 solver when i write an equation with letter the calculator ask for the values to be assigned to each letter. What should I do to get the same function on the new calculator ?

You must have been using the solver Application on TI89 (or you were using a program)... and there isn't such an Application on TI Nspire CAS (and few programs doing that).

But, there is a function "solve" which is very easy to use (exactly as there was one on TI89 !) and in which you can specify each variable if needed.
See

Code: Select all

solve(my_equation,my_var)|var1=val1 and var2=val2 and...

the solve function is the same of ti89, but on it the equation solver ask for the value of the letter in automatic mode. is it possible on ti nspire cas?

however, I've always used the numeric solver that you can find in the ti 89 menu

Ctrl+Enter instead of Enter, or use nSolve instead of Solve.
