WebTrigonometric functions don't "preserve" units. The expression under a trigonometric function must be dimensionless and so is the value of a trigonometric function. Thus, C2 in your equations is in units of frequency: Hz or 1/s. There is an error in one of the equations, perhaps a missing constant. Share Cite Improve this answer Follow
