tanRCx
TanRCx is a compact notation used in some mathematical and engineering contexts to denote the tangent of the product RCx, where R, C, and x are real quantities. The exact meaning depends on the setting, but a common interpretation is tanRCx = tan(R C x).
If R, C, and x are real numbers and RCx is dimensionless, then tanRCx = tan(R C x).
In electrical engineering and physics, RC typically denotes the resistance-capacitance product, sometimes forming a time constant
Example formulations: with R = 1 and C = 1, tanRCx reduces to tan(x). At x = 0.5, tanRCx
