help?

OpenStudy (anonymous):

When would the cosine of a number be equal to the sin of that number+20? To help attack the problem, you have to have an understanding of sin and cos / the unit circle. At what degree # (remember, only 0-90) are sin and cosine equal?

OpenStudy (ilovebmth1234):

idk im not good with sin and cosine

i dont know...

OpenStudy (ilovebmth1234):

that link is blocked on my computer

OpenStudy (daniel.ohearn1):

What antivirus do you use?

OpenStudy (ilovebmth1234):

i see it now and can you explain? that was a whole page of TF to me lol /.\ and idk my school has curtain programs they put on this computer to block stuff

OpenStudy (daniel.ohearn1):

Unit circle gives you values for sin(x) and cos(x) for values x between 0 and 2pi radians or 0 and 180 degrees, it just so happens that both graphs intersect at pi/4

OpenStudy (daniel.ohearn1):

when were concerned with 0 to pi/2 x values

Wolfram Alpha might help too to verify

OpenStudy (aishalicious1):

@Kainui can you explain this well enough and easy?

OpenStudy (a_burning_masquerade):

I'm so sorry but I have no idea. I'm good at algebra but not when it comes down to figuring out all the distance between this shape and that. I'm sorry but I won't be much help with this particular question.

OpenStudy (a_burning_masquerade):

I wish I could provide the answer but I can't.

OpenStudy (ilovebmth1234):

its alright
