The voltage signal from a standard North American wall socket can be described by the equation V(t)=170sin120(pi)(t), where t is time, in seconds, and V is the voltage, in volts, at time t.
a) Find the maximum and minimum voltage levels and the times at which they occur.

The answer is a max of 170 and a min of -170, but I have no idea how they got that answer

cggurumanjunath · Answer

number before v(t)=170*sin(pi*t) is the answer ! (170)

anonymous · Answer

Yes the answer is a max of 170 but how do you get that answer becuase don't you have to find the derivative of it first before finding the max and min

cggurumanjunath · Answer

no !

anonymous · Answer

So you don't find the derivative of the equation?

cggurumanjunath · Answer

no .... u need not find derivative here !

anonymous · Answer

Oh ok because for the previous questions like this one i needed to find the derivative of the equation to find the max and min

cggurumanjunath · Answer

ok.
