Can someone please help me out here with an equation I need to minimise? My efforts don't seem to be correct when I plot em in excel. Thanks all and apologies for the lack of Latex use.

v = 1/(cos(x) + c.sin(x))

.... where c is a constant.

f ' =[ sin(x)-ccos(x)]/[(cos(x)+csin(x))^2]

f ' = 0 when sin(x)-ccos(x) = 0

tan(x) = c

x = arctan(c)__+__2pi - Aug 19th 2009, 06:28 PMmgri
Great stuff. Thanks!
