A question from a recent Praxis II exam states which has more roots between 100π and 1000π?
thanks for your help
If cos(x)^2 means cos(x^2) then it will win, it has an absurdly large number of roots in that domain compared to the other two.
If cos(x)^2 means (cos(x))^2 then it will be a tie with cos(x)
The one with the root has very few roots in the domain compared to the other two.
