What is the voltage across a resistor in an electrical circuit?

Homework Statement

The voltage V(t) [in volts] across a resistor in an electrical circuit at a given time t [in seconds] is given by:

sqrt of something to the power of pi

^ that's the example i got in my book. Its just got the square root symbol, a space, and then a pi in an exponential position.

power as a function of time: p(t)=v(t) · i(t)

Ohm's Law: v(t)=R · i(t)

The nearest matching your case that I can see is p(t) = (v(t))² /R
when rearranged to v(t) = ...

No power of Pi.

Im very confused too. I thought i must have been missing something. Ill bring it up with the teacher.

Thanks mate
