The period of the sin(4x+π2) function is π2 so values will repeat every π2
radians in both directions.
x=Ï€8+Ï€n2,3Ï€8+Ï€n2
, for any integer n
Consolidate the answers.
x=Ï€8+Ï€n4
, for any integer n
How do I know when to consolidate answers? What should I look for? (I know if they are pi apart they repeat)
