Hi. First post on forum. Hopefully in proper section. I have a question like this;
The graph shows output model of vibrations of engine, and can be expressed function;
[FONT="] x(t)=(cos[/FONT][FONT="]π[/FONT][FONT="]t)(sin20[/FONT][FONT="]π[/FONT][FONT="]t) [/FONT]
For what values of t in interval 0-1 the amplitude x(t) is zero? Hint; evaluate sin nπ for integer values of n
