The voltage in a circuit is given by the formula V = 16t3  79t. Find the values for t for which V is a maximum or a minimum.
larger t in seconds =
smaller t in seconds =
My Answer:
V=16t^379t
V'=48t^279
0=48t^279
Sq root of 1.645833 = t
1.2829= t
V''=96t positive therefore a min
Larger t = 1.2829
smaller t = 1.2829
Can you please confirm this is correct.
