What is the maximum value for 't' and what is the resolution of 't' , and the range for 'i'? What precision do you need for the result?

If you want to use a Look-Up Table you will need ((tmax / resolution(t)) * precision) memory bits. If that exceeds the number of available you will have to find a (mathematical) solution to compute the result.
