Thank you!
helpsos
  • helpsos
okay, so I think I have it figured out. What was first step when solving number 11?
matlee
  • matlee
I think it was FOIL or just multiply terms
helpsos
  • helpsos
yup, what did you end up with?
helpsos

Do you know the basic identity for what Cot is equal to? for example: tan= sin/cos
matlee
  • matlee
i think sin/cos
matlee
  • matlee
So i guess i dont not know any of thi, so i would have to learn what formula make which sign?
helpsos
  • helpsos
Sin/ Cos is the identity for Tan. For Cot, the identity is Cos/Sin. The next step to simplifying the equation would be to turn everything complex, into it's simple form. For example, turn the Cot into Cos/Sin. And turn Csc into 1/Sin
helpsos
  • helpsos
Yes, did your teacher give you a formula sheet?
matlee
  • matlee
OH I SEE! Thanks
