would i be correct?! Find the solution set of the given equation for 0 ≤ x ≤ 2π. -5 - 2cosx = -6 {pi,2pi/3} {pi,5pi/3} <<< i chose this (:
@hartnn how about for this one?? Find the solution set of the given equation for 0 ≤ x ≤ 2π. -tanA = -1 {pi/4,3pi/4 } <<?? {pi/4,5pi/4 } {3pi/4,5pi/4 } {3pi/4,7pi/4 }
nopes, tan pi/4 =1 but tan 3pi/4 is not 1
then it would be pi/4, and 5pi/4 perhaps?
