Find the exact value of the real number y. y = csc^-1(1)
help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
@RadEn do you get this one??:0
@zepdrix do you know this??
@aaronq do you have any idea??
@SithsAndGiggles ............wanna help?
please help:(
I see you messaged everyone you know.
haha yes i was desperate :( but no one helped me though....;(
Just type in arccos(1) into wolframalpha.com
It's a pretty good website when it comes to math.
ohhh they said 0 but i need it in a pi form.......@LordVictorius
@LordVictorius
It gives it in that form.
Try it.
\[\large y=arccsc(1) \qquad \rightarrow \qquad \csc(y)=1\] Recall that \(\large csc(x)=\dfrac{1}{sin(x)}\) Which gives us,\[\large \frac{1}{\sin(y)}=1 \qquad \rightarrow \qquad \sin(y)=1\]At what angle does the sine function give us a value of 1?
I'm not sure how you came up with zero, did you punch it into Wolfram correctly? :O http://www.wolframalpha.com/input/?i=y%3Darccsc%281%29
@zepdrix um....pi or 2pi?
Don't you remember your special angles? D: Go back to your unit circle, you must have one lying around somewhere!! c:
Type, "Unit Circle" into google.
@zepdrix ohhhhh pi/2 right?
Yes c: good.
@LordVictorius okay:D
@zepdrix that's the answer?
Yes.
thankyouuuuuu!
