If your application is not critical you can use a small LUT e.g. 256 points then interpolate (linearly) between two values as they occur by finding the difference between input (t) value and nearst LUT values. i.e. some t values will point directly, most others will point in between LUT points so a basic calculation is needed to adjust the result.
