Rounding Errors

Trig Triumph rounds the final answer to the nearest thousandth (3 digits after the decimal point). Often rounding each step in a series introduces rounding errors. The final result may be too high, when more than one step in the series rounds up. The final result may be too low, when more than one step in the series rounds down.

Avoid rounding while playing Trig Triumph. Perform each step, then let the game round the final answer. The Trig Triumph game allows for small rounding differences. However it's helpful to understand for future math projects.
