Exact Mode

Exact mode attempts to return an exact result to a calculation, similar to the answers required in most math classes. Exact answers may contain roots, constants, and unresolved expressions rather than a decimal answer.

Example Outputs

√8 = 2√2	π/4 + π/3 = 7π/12
√8 + √18 = 5√2	(4 ± √8)/2 = {2 + √2, 2 - √2}
sin(π/4) = √2/2 (radians mode)	asin(√2/2) = 45 (degrees mode)

Notes

The inclusion of any non-exact or decimal value in a calculation will result in the calculation returning a decimal (non-exact) answer. Some calculator functions are implicitly non-exact even if the result of a particular calculation may have an exact answer (i.e., log, ln, stat functions, etc.). Trig functions are only exact for certain angles (30°, 45°, etc.).

Exact mode will attempt to simplify answers by combining like terms, rationalizing denominators, etc., but it may not always simplify the answer as completely as possible. For instance, no attempt is made to rationalize denominators using complements.
