Question 289562
i am supposed to graph y=3cosx and y=sin(3x) on the same axes. i am having trouble. please help me. thank you

plug in values for the first function and plot those then do the same with second function

{{{ graph( 500, 500, -10, 10, -10, 10, 3*cos(x), sin(3*x) ) }}}

in y=3cosx, the amplitude increased 3 times
in y=sin(3x), the frequency increased 3 times
