Question 905482
The cosine wave gets expanded in both + and -
y-directions by the factor of {{{ 3 }}}
------------
The phase of the cosine wave gets shifted by almost
{{{ pi = 3.141 }}} ( if {{{ x }}} is in radian measure )
--------------------------------------------
Here's the plot:
{{{ graph( 600, 300, -10, 10, -5, 6, 3*cos( x+3 )) }}}
At {{{ x = 0 }}}, the cosine would normally be {{{ 3 }}},
but it is almost {{{ -3 }}} due to +3 phase shift
