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 =
Sq root of 1.645833 = t
V''=96t positive therefore a min
Larger t = 1.2829
smaller t = -1.2829
Can you please confirm this is correct.
