do you know what range is?

And also, do you know what the graph of a sin function looks like?

i do not @FireKat97

  • FireKat97
wait, what is it that you don't know? range? the graph of a sin function? or both?
anonymous
  • anonymous
little bit of both
FireKat97
  • FireKat97
okay, so the range basically describes all the y values a particular function can possibly have, so for e.g. |dw:1443789985087:dw| the range of this function would be -3 ≤ y ≤5 do you see what I mean?

  • anonymous
yeah so how would i find what i need
FireKat97
  • FireKat97
So for your particular question, you need to be familiar with the sin function which looks something like this |dw:1443790151790:dw|

now in this particular question, we are asked for the range, for when the domain is -π ≤x ≤0 which is in this section |dw:1443790370016:dw|
FireKat97
  • FireKat97
so we have to apply our knowledge of what a range is, in order to be able to recognise the range for the section above, so what do you think the range would be in this case?

A. and honestly this made me feel so retarded
FireKat97
  • FireKat97
yup thats correct! and why so?
anonymous
  • anonymous
because you described it like it was nothing
FireKat97
  • FireKat97
oh, I'm sorry if my explanation was badly phrased/worded :/
anonymous
  • anonymous
its ok i already knew im retarded
FireKat97
  • FireKat97
hey! don't think that way -_- seriously, you grasped the concepts pretty quickly, you should be proud of yourself
