I sometimes hear these two words used interchangeably.

Problem:
These two words are not synonyms.

The primary definition of the word “determinate” as a verb is to make certain of. The primary definition of the word “determinate” as an adjective is having defined limits.

The primary definition of the word “determinant” as a noun is a determining agent. The primary definition of the word “determinant” as an adjective is having the power of deciding.

I believe that these words most often are used interchangeably because of sloppy pronunciation.

When using each of these words as an adjective, think having defined limits for “determinate” and having the power of deciding for ” determinant”.
