Question

подскажитепожалуйсто косинус 405 градусов

Answer 1

Cos(405)=cos(360+45)=cos 45= √2/2

Answer 2

Косинус отрицательного числа равен косинусу положительного, следовательно смело можем ставить Кос (405)=Кос (360+45)=кос (45)=Корень (2/2).

Answer 3

Косинус 405 градусов равен cos(405) ≈ -0.9397.

The cosine function is a mathematical function that relates the angle of a right triangle to the ratio of the length of the adjacent side to the hypotenuse. In this case, we are looking for the cosine of an angle of 405 degrees.

According to the search results, the cosine of 405 degrees is approximately -0.9397

Please note that angles in trigonometry are typically measured in radians rather than degrees. To convert degrees to radians, you can use the formula: radians = (degrees * π) / 180. In this case, the equivalent angle in radians would be (405 * π) / 180.
