Hi,how do I find both solutions of the equation cos0 = 0.35 between degrees 0 and 360?
the cosine is positive in the I and IV quadrant
using the inverse cosine function on your calculator
Ø = 69.513°
so Ø is either 69.513° or (360-69.513)° or 290.487°
i hope this is not ou question? as this is the exam cheat
