@SamLawrence08 @pearson Turns out that the validation is even more interesting than I thought in that the (x-1) and the (y+3) are the generalized run and rise for any radius for that circle, so when any point on the circle is substituted for the "other" (x-1) and (y+3) they give the tangent equation

[Susan Wildstrom @wildmathlady]

@SamLawrence08 @pearson It is valid and always works. The basis has to do with a clever observation about the form of a line that is perpendicular to a given line. The tweet space is too short to explain fully though. Contact me directly if you want a thorough proof

@maanow I loved Lida. She was always so kind and welcoming to me

@brooke Keep up the good work. No, you are NOT 80, but I hope you will live to be that and more! What is the puppy you weren't going to get's name? And I hope you received (way back when) the scarf I sent to match your tie-dyed sweatsuit!

[Susan Wildstrom @wildmathlady]

All the years I taught multi I would have liked to have had this for just that intuition about divergence and curl!

[Steven Strogatz @stevenstrogatz]

Brilliant exercises for developing intuition about divergence and curl, from Purcell’s book on electricity and magnetism. “Four of these vector fields have zero divergence in the region shown. Three have zero curl. Can you spot them?” (I’ll show solutions lower in the thread.)

[Susan Wildstrom @wildmathlady]

@brooke So what is your new puppy's name?

[Susan Wildstrom @wildmathlady]

@brooke The leftovers are often as good as the original meal! I hope you are fully recovered now

[Susan Wildstrom @wildmathlady]

My Thanksgiving FEAST thanks to Jon, Carla and the grandkids. I even had a nice outdoor visit with them while the turkey cooled

[Susan Wildstrom @wildmathlady]

@SteveSchmidtSES From your mouth to God's ears. I am a nervous wreck and think my blood pressure has gone through the roof!

Is trump paying royalties to @eltonofficial and @billyjoel for using their music at his stupid rallies?

[Susan Wildstrom @wildmathlady]

Trump shouldn’t make fun of @JoeBiden and his drive-in rallies. At least his supporters have a way to get home afterward and don’t have to wait in the freezing weather for buses that don’t show up

[Susan Wildstrom @wildmathlady]

@brooke I don't ever look that good and I haven't had surgery! Hope the recovery continues to be a smooth one.

[Susan Wildstrom @wildmathlady]

@brooke @Natalie_Rix @jazminbaeltran @Jasonwilk @davesavesyou Looks like a comfy outfit to wear during your recovery, and it looks great on you!

[Susan Wildstrom @wildmathlady]

@brooke That's a bit too extreme for me. I think I might just have to settle for being able to turn the television OFF (but I am probably too obsessive to be able to actually do that). Hope the surgery goes well.

[Susan Wildstrom @wildmathlady]

@brooke @PCMNewsletter I somehow missed the part about your needing heart surgery. Sending good vibes, wishes, and prayers your way and looking forward to your speedy recovery and return.

[Susan Wildstrom @wildmathlady]

@brooke Someone told me to use hair spray for bugs (even small ones drive me crazy—Stephen used to have to dispose of them). It stuns and then paralyzes them (strong holds them in place!),

Watch “Something New Every Day” on #Vimeo https://t.co/ZJWU2JPZSN The world lost an icon of mathematics Tuesday when Ron Graham passed away. His legacy, however, will live on through his books, research, and the many students he taught and mentored, one of whom is my son, Jake

[Susan Wildstrom @wildmathlady]

@brooke @nysdmv I live in New York if I can somehow help
