CIRCULAR TTI]NCTIONS AND TRI(;ONOMEI'ITY

5. Functions ofthe form y: - f(x) and y: f(-x)

For -2r 1x<4tr, sketch the graph ofthe function y: cosx and y: - cos x onthe
salne axes-

For -2r <x<4tr, sketch the graph ofthe function y = cos x and y: cos(- x) on the
same axes,

ll/hat transformation would move y =cos x lo y : - cos x dnd y: cos (x)?
