[sympy] Introducing myself and my interests

Hi everyone, My name is Anshil Gandhi and I am a first year student at the University of Alberta, enrolled in B. Sc. Honours in Computing Science. I am fairly experienced with programming and algorithm design. I began writing programs when I was in grade 3 in a language called BASIC. I have

Hmmm...try again: >>> var('r:4 m2') (r0,r1,r2,r3,m2)(r0,r1,r2,r3,m2) >>> m=sqrt(m2) >>> _m2 = r0**2 + r1**2 + r2**2 >>> m.diff(m2)*_m2.diff(r0) r0√m2r0m2 >>> (m.diff(m2)*_m2.diff(r0)).xreplace({m2:_m2}) r0√r20+r21+r22r0r02+r12+r22 >>> sqrt(r0**2+r1**2+r2**2).diff(r0) r0√r20+r21+r22r0r02+r12+r22

Did you mean this? >>> var('r:4 m2') (r0,r1,r2,r3,m2)(r0,r1,r2,r3,m2) >>> m=sqrt(m2) >>> _m2 = r0**2 + r1**2 + r2**2 >>> m.diff(m2)*_m2.diff(r0) r0√m2r0m2 >>> (m.diff(m2)*_m2.diff(r0)).xreplace({m2:_m2}) r0√r20+r21+r22r0r02+r12+r22 Without the chain rule this can be computed as: >>>

Interesting that you should mention this. See the recent thread here where I ask if there is a better way to compute such things (at least to a novice it appears that we are talking about the same thing). On Thursday, February 15,
