# An electric current, I, in amps, is given by I = cos(wt) + √5 sin(wt) where w does not equal zero is a constant. What are the maximum and minimum values of I?

An electric current, I, in amps, is given by

I = cos(wt) + √5 sin(wt)

where w does not equal zero is a constant. What are the maximum and minimum values of I?

Minimum value of I:

Maximum value of I:

(I became stuck after taking the derivative and setting the function equal to zero... Thanks for the help!!)
