Mothers Law

Mother's Law; noun
The Mother version of Murphy's Law.

As originally defined in Mikayla's Dictionary published 2024;
When a mom's time and motivation align perfectly to complete tasks otherwise usually pushed aside for lack of time or motivation alignment, the Mother's children will then undoubtedly become extraordinarily clingy, perform dangerous acts and hurt themselves requiring comfort and consoling, fight with siblings (both verbally and physically) and cause various alternative chaotic acts within the home environment, therefore causing the tasks or projects to yet again go undone or possibly worsen.
I finally had the time and willpower to (insert task here) but then the kids went feral - that's Mothers Law for you!

Law of Cosines

the worst shit you could ever witness in solving oblique triangles; more painful than Law of Sine.
“Dude, are why the fuck do we even have LAW OF COSINES”

“idk bro but it's lowkey fun, here r the formulas”

Formulas FOR SIDES:
a² = b²+c²-2bc cosA
b²= a²+c²-2ac cos B
c²= a²+b²-2ab cos C

Formulas FOR SIDES: (always use cos-¹ to solve for angles)

cosA : b²+c²-a² / 2bc
cosB: a²+c²-b²/ 2ac
cosC: a² + b² / 2ab
