I am using msdn and vb6 and msdn does not in any sence of the word make much sence at all :p

delta_theta =- (theta + sin(theta) - constant) / (1.0 + cos(theta))

1) delta_theta =delta_theta - (theta.....

or

delta_theta =-1*(theta+sin(......

thanks again another one solved.....

theta += delta_theta

does this mean;

1) delta_theta = 2 * theta

or

2) theta = .5 * delta_theta

thanks

So it would read:

if t_x not less then pi then x=x-sign(x) *(2*pi)

Correct??

Sorry it should be:
x = (t_x < pi)? x: (x - ( sign( x ) *( 2*pi) ))

can someone help me translate this into visual basic

x = (t_x < pi)? : (x - ( sign( x ) *( 2*pi) ))

function sign(X)
just returns a 1 if x is positive and a -1 if it is negitive
