The cleanest trick in calculus. ∫ sec(x) dx = ? Multiply by (sec(x) + tan(x))/(sec(x) + tan(x)). The numerator becomes EXACTLY the derivative of the denominator. Let u = sec(x) + tan(x) → ∫ du/u = ln|u| + C. ∫ sec(x) dx = ln|sec(x) + tan(x)| + C ✓ Follow @dailymathvisuals for daily visual math. Shop: dailymathvisuals.lemonsqueezy.com

Can 3 cuts make 8 pieces? Flat pizza: max 7. Thick cake: 8. 2D: 1 + 1 + 2 + 3 = 7. (max with n cuts = 1 + n(n+1)/2) 3D: 1 + 1 + 2 + 4 = 8. In 2D each cut is a line. In 3D each cut is a plane. Dimension does the rest. Follow @dailymathvisuals for daily visual math. Shop: dailymathvisuals.lemonsqueezy.com

Math contest Q39 — A cubical sponge absorbs water at 2 in³/min. How fast is the edge growing when V = 8 in³? V = s³ dV/dt = 3s²·(ds/dt) At V = 8 → s = 2 2 = 12·(ds/dt) → ds/dt = 1/6 in/min ✓ Answer: (b) Follow @dailymathvisuals for daily visual math. Shop: dailymathvisuals.lemonsqueezy.com

@Meta @MetaforBusiness @facebook @instagram @boztank @andymstone @mosseri @NOBFixx Would be able to help on this one please?

@dailymathvisual @Meta @MetaforBusiness @facebook @instagram @boztank @andymstone @mosseri One of the best tech advisors I’ve worked with. Quick and effective solutions.

@Tokfno @Nobfixx Meta support team hasn't responded to the support emails raised. Not even an acknowledgment for the case.

Have you sent an email to the support team?? I was referred to this cyber security expert by a colleague who was a former Meta employee, and twitter X he’s the best partner's with Meta any kind of recovery,you should contact him for help @NOBFixx on Twitter support

@Tokfno @Nobfixx Thank you @justjp5 I have reached out to @Nobfixx

I think their support system is out of service because I also tried all platforms to contact them to resolve same issue and it was of no use, I will advise you check @nobfixx ON X am sure he can fix the issue because he also fixed mine

@Meta @MetaforBusiness @facebook @instagram @boztank @andymstone @mosseri My Business Manager has been hijacked. The unauthorized admin has Full Control of my account, and the email shown for them has CHANGED since the compromise, confirming active tampering. The current email is fbbbsupporrtteamin@gmail.com, which is not a real Meta support address — it's a deliberate impersonation of "FB Support." I'm the legitimate owner of @dailymathvisuals. Business Manager ID: 1332629101972277. Date of compromise: June 10, 2026. I've submitted 4+ reports through official Meta channels and received zero response. Please help — this needs to go to your Trust & Safety / impersonation team, not standard account recovery.

@Meta @MetaforBusiness My Business Manager has been hijacked. On June 10, 2026, an unauthorized user gained Full Control admin access to my Business Manager without my consent. I am the legitimate owner of @dailymathvisuals, a small educational math channel. The unauthorized admin currently shows as fbbbsupporrtteamin@gmail.com — which is a Gmail address deliberately impersonating Meta support, and the email has been changed since the initial compromise, confirming active tampering. My Business Manager ID is 1332629101972277 and my account email is purush.ramalingam@gmail.com. I have submitted four reports through official Meta support channels and received zero response. I have signed up for Meta Verified for Business with no chat support made available. I have attempted in-app removal of the unauthorized admin, blocked because they hold the higher role. Please escalate this to your Business Integrity / Trust & Safety team — specifically the impersonation queue, not standard account recovery. I am willing to verify my identity through any method Meta requires. Screenshot of the unauthorized admin in the People list attached.

Find the 2025th derivative of sin(x). Derivatives of sin cycle every 4: sin → cos → −sin → −cos → sin So only n mod 4 matters. 2025 = 506·4 + 1 2025 ≡ 1 (mod 4) Answer = 1st derivative = cos x ✓ Follow @dailymathvisuals for daily visual math. Shop: dailymathvisuals.lemonsqueezy.com

What's the area under y = x² from 0 to 1? Your eyes want to say 1/2. It's 1/3. Slice into rectangles → sum converges to 1/3. That limit-of-sums is what ∫₀¹ x² dx means. Shortcut: antiderivative of x² is x³/3 → [x³/3]₀¹ = 1/3. Same answer. That's the Fundamental Theorem of Calculus. Follow @dailymathvisuals for daily visual math.
