WebFeb 11, 2024 · I was solving a question and got struck in a sub-question which is, If x = cos1°cos2°cos3°⋯cos89° Find the value of x. I don't actually have any idea on how to proceed on this question. Any hints are welcome. The answer given in the book is a perfect integer 17. Do you know cos(x)cos(y) = cos ( x + y) + cos ( x − y) 2? WebIn the figure above, cotα = b / a, and cotβ = a / b. A cotangent of an angle α is also equal to the ratio between its cosine and sine, so cotα = cosα / sinα. Following from the definition, the function results in an undefined value at certain angles, like 0°, 180°, 360°, and so on. Related trigonometric functions
