Hi,

 

I'm new to the physics package - wondering if i can tweak it a bit to look like things i'm used to:

 

is there a way to make Christoffel symbols print as upper case gamma, instead of  'G'?

KroneckerDelta print as lower case delta, instead of 'd'?

 

can i make the Schwarzschild metric look like it does in Hartle, Carroll, and others:

 

-(1 - 2M/r)dt^2 + (1-2M/r)^-1 + r^2(dtheta^2 + sin(theta)^2 dphi^2)

 

i know about setting the signature in Setup.

i have tried the 'Coordinates' command, but when i give it X=[t,r,theta,phi] i always seem to get back

[t,r,q,f]

 

i am running maple 2016

 

many thanks,

larry
