Hi, this seems very basic, but I wasn't able to figure it out. Let's say I have a function:
sage: f(t) -4*(5*sqrt(2)*cos(1/2*sqrt(2)*sqrt(5)) - 2*sqrt(5)*sin(1/2*sqrt(2)*sqrt(5)))*sin(1/2*sqrt(5)*t)/(sqrt(5)*sin(1/2*sqrt(2)*sqrt(5))^2 + sqrt(5)*cos(1/2*sqrt(2)*sqrt(5))^2) + 4*(5*sqrt(2)*sin(1/2*sqrt(2)*sqrt(5)) + 2*sqrt(5)*cos(1/2*sqrt(2)*sqrt(5)))*cos(1/2*sqrt(5)*t)/(sqrt(5)*sin(1/2*sqrt(2)*sqrt(5))^2 + sqrt(5)*cos(1/2*sqrt(2)*sqrt(5))^2) - 8 how do I tell sage to evaluate numerically everything but sin(), cos() and t? I.e. I know this function is in the form f(t) = a*sin(b*t) + c*cos(d*t) can I tell sage to put it in this form, evaluating numerically a,b,c and d? kind regards renato -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
