Trigonometric function calculating device

A trigonometric function calculating device comprising at least one processor and at least one memory, wherein:

• the at least one processor is configured to generate an address signal that is formed from a plurality of bit strings and that corresponds to a phase;
• the at least one memory stores a trigonometric function table that includes first sines and first cosines that respectively correspond to phases expressed by upper bits of the address signals, and second sines and second cosines that respectively correspond to phases expressed by lower bits of the address signals;
• the at least one processor is configured to output, as a calculated value, a cosine that corresponds to the address signal by calculating processing using the first sine, the first cosine, the second sine and the second cosine that correspond to the address signal and have been extracted by referring to the trigonometric function table;
• and
• the at least one processor is configured to correct the calculated value on the basis of a correction value that corresponds to the address signal.
