Which infinite series test should you use?

Pattern first. Test second.

Learn p-test, geometric, comparison, Ratio, Root, Integral, alternating, telescoping tests.

@WatcherGuru Again?

Epsilon-delta proofs become manageable when you stop guessing δ.

Factor the error, build a local bound, choose δ, then write the proof forward. Complete example: lim(x→2) x² = 4.

When standard ODE methods fail, build the solution coefficient by coefficient.

Assume → Differentiate → Substitute → Reindex → Recur

Closed surface? Check divergence first.

Learn how the Divergence Theorem converts outward flux into a volume integral—and see a complete sphere example.

Euler’s Method uses the current slope to step forward and approximate a differential equation solution. Learn the formula, build the table, understand step size, and avoid common mistakes.

Group theory begins with four axioms: closure, associativity, identity, and inverses. See how ℤ₄, Cayley tables, generators, and triangle symmetry make algebra visual.

@TheBTCTherapist Then why is Black Rock selling. JP Morgan did the same thing when they bagged on BTC then bought when they crashed it.

@carlmoon See you all in 3 years.

@cryptorover This whole presidency has been one giant get rich quick scheme for Trump and his family. A leopard does not change its spots.

[Woody Calculus @WoodyCalculusX]

@TheBTCTherapist It total makes sense. We got conned. Crypto president has been shorting crypto prior to his tariff announcements all year. A leopard doesn’t change its spots. Wake up.

[Woody Calculus @WoodyCalculusX]

@TheBTCTherapist All caps doesn’t make it true.

[Woody Calculus @WoodyCalculusX]

@BBCWorld Guess who gets to pay for that.

[Woody Calculus @WoodyCalculusX]

@TheBTCTherapist The world does not respect him.

@DanielSeuss @scottmelker And which one are you?

@MarioNawfal @TheAroraReport Didn’t we just fall for this in Venezuela ?

[Woody Calculus @WoodyCalculusX]

@TheBTCTherapist Didn’t we just fall for this same BS in Venezuela? Give me a break!

[Woody Calculus @WoodyCalculusX]

@TheBTCTherapist Just like the last president, Trump doesn’t know what planet he is on. He’s just bolder than Biden. He’s making a mess.
