Answer 2

Answer:

There's a lot but here are the basic ones. (sinx) ^2+(cosx)^2=1 1+(tanx)^2=(secx)^2 1+(cotx)^2=(cosecx)^2 Sin(90-x)=cosx and vice versa sec(90-x)=cosecx and vice versa tan(90-x)=cotx sin(a+b)=sina*cosb+cosa*sinb sin(a-b)=sina*cosb-cosa*sinb cos(a+b) =cosa*cosb-sina*sinb cos(a-b) =cosa*cosb+sina*sinb tan(a+b) =(tana+tanb) /1-tana*tanb cosecx=1/sinx secx=1/cosx cotx=1/tanx
