Mario's cosine also the exact opposite of Mario.
mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
The value of the cosine of 55 degrees is approximately 0.5736. This value can be found using a scientific calculator or trigonometric tables. Cosine values are used in various applications, including physics and engineering, to analyze angles and distances.
Cosine cannot have this kind of high value, it ranges from -1 to +1
It doesn't exist. The maximum value of the cosine is 1.00, so no angle can have a cosine of (pi), because (pi) is more than 3.
cos(15 deg) = 0.9659, approx.
