👉 In mathematics, a "side hold" is a type of mathematical operation that involves taking two or more sides and performing an operation on one side while leaving the other side unchanged. This is often used in trigonometry to simplify certain equations involving sine or cosine functions. For example, consider the equation: \[ \sin(2x) = 2\cos(x)\] If you were to apply a "side hold" operation that left the other side (i.e., x) unchanged,
