Cos 30. Things To Know About Cos 30.

The name cosine comes from the Latin prefix co-and sine function – so it literally means sine complement. And, indeed, the cosine function may be defined that way: as the sine of the complementary angle – the other non-right angle. The abbreviation of cosine is cos, e.g., cos(30°). Important properties of a cosine function:Tentukan Nilai yang Tepat cos(30 derajat ) Step 1. Nilai eksak dari adalah . Step 2. Hasilnya dapat ditampilkan dalam beberapa bentuk.
