I got a strange question on here: The power P in a circuit is P = RI^2, where R is the resistance and I is the current. Find dP/dt at t = 1/16 if R = 3,000 watts and I varies according to I = sin(4pi(t)) Now my question is is it asking to divide the derivative of p by the derivative of t or to find the derivative of p in respect to derivative t?

in respect to

OpenStudy (fibonaccichick666):

that's just standard notation for that, just like you can have dx/dt or dy/dt

OpenStudy (fibonaccichick666):

or dy/dx

OpenStudy (fibonaccichick666):

and with respect to t not the derivative of t

OpenStudy (fibonaccichick666):

aka, find the derivative of power

ah got it thanks!
