If cosx= -1/2 for 90degrees<x<180degrees, calculate cosx/sinx

sec(90degrees -theta)

1-cosx/1+cosx=(cotx-cscx)^2

square root of (1-cosx/1+cosx) = cscx - cotx prove the identity

cotA = tan(90degrees- A) True or False The vectors <4, 5> and <-10, 8> are orthogonal True or Fal...

integrate:cosx+2/cosx+sinx

Prove that 1+cosx+sinx/1-cosx+sinx=cotx
