WebInverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y. Example. arccos 1 = cos-1 1 = 0 rad = 0° See: Arccos function.

"WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle. We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments. " - Cosine of 23
