what are the Pythagorean Identities? |
Sin^2 (u) + Cos^2 (u) = 1 1 + Tan^2 (u) = Sec^2 (u) 1+ Cot^2 (u) = Csc^2 (u) |
|
What are the identities that involve pi/2? |
Sin ( pi/2 - u) = Cos (u) Csc ( pi/2 - u) = Sec (u) Tan ( pi/2 - u) = Cot (u) |
|
What are the double angle Identities? |
sin 2(u) = 2sin(u)cos(u) cos 2(u) = cos^2(u)-sin^2(u) = 2cos^2(u) - 1 = 1- sin^2(u) tan 2(u) = 2tan(u)/1-tan^2(u) |
|
