  • Thank you for the explanation, you are the best. I wonder though why the bastards put advertising even in educational videos, no respect

  • So as a general rule are you always dividing by 2 to get the intervals for your graph, or was it just in this case?

  • @patrickJMT I'd like to know the answer for the above question also. would u mind explaining it to me plz? Do we always set it equal to pi/2 or it depends? I'm really confused about this. and the fact is that me prof never explained me how to find this. all he did was: cos(2theta) => period = Pi? Thanks in advance!

  • should i always set it equal to pi/2 to find the increments? or does that only apply for this problem??!?!?!?!?!

  • omg, thank you thank you thank you so much, i got it!

  • @annie2198 Totally agree.. You make so much more sense than my teacher!! :D :D

  • Honestly, I owe my grade to you Patrick. Thank you VERY much, If I become rich one day, I will keep you in mind :)
