Can value of sin(x) be positive?View attachment 23007View attachment 23009
So i want to find if this series diverges or converges but i really can't figure it out.I can't even start to prove it .Any help?Thanks!!!
Basically, this is how the problem was given to me.For the first series i can't even get started, but for the second one i thought of using D’ AlembertCan value of sin(x) be positive?
Can value of sin(x) be negative?
Does the sign of sin(x) remain constant through the domain of summation?
What does that indicate?
