Question 967309
Could someone help me graph the following functions and find their points: 
1. y=1/2cos(1/4*x)
{{{graph(400,400,-2pi,2pi,-2,2,(1/2)cos(x/4))}}}
--------------------------------- 
2. y=-2-3sec(x-π/2)
{{{graph(400,400,-2pi,2pi,-10,5,-2-3(1/cos(x-(pi/2)))))}}}
----------------------------------
Cheers,
Stan H.
