Web17 apr. 2024 · This formula expresses the sine function as an alternating series: To make sense of this formula, use expanded notation: Notice that this is a power series. To get a quick sense of how it works, here’s how you can find the value of sin 0 by substituting 0 for x: As you can see, the formula verifies what you already know: sin 0 = 0. Web29 mrt. 2024 · So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine." Please give me brainiest.
