- TL;DR Summary
- Time t value of SIN function should be calculated to get a SIN function value of -1

Hi,

I am new here and hope I have posted my thread in the right forum.

I have the following SIN function in Excel: =1*(SIN(2*PI()*1,6667*0,45))

The result is -1. That is what I want, so no problem.

But what I want is a function that calculates the Time t value, in this example the value 0.45, that results the SIN value -1.

So the function is: 1*(SIN(2*PI()*1,6667* x )) = -1.

How can I calculate x (Time t)?

Thank you all very much for your assistance.
