# How to use wolfram alpha to plot frequency response

Void Xylem
Can someone please tell me how I can plot the magnitude and phase response of this transfer function on wolfram alpha as I don't have Matlab:

H(s) = -(2.1953*10^12)/(66600*((j*ω)^2)+808823539.4*(j*ω)+2.1626*10^12)

A link to the output would be very useful also, thanks heaps.

You can use abs(...) and phase(...) with i as the imaginary unit.

thanks bro, your post has improved my life quality by a factor of 0.0001, one more question: How do I make it plot the phase in degrees instead of radians.

You can also use 'bode (...)', which will plot the amplitude and phase in degrees. As a bonus you get Nyquist and Nichols too :)

haha wow that's really cool, its going to be very useful, i got to admit i have no idea what the Nyquist and Nichols are atm but ill get there eventually. thanks for the help.
