Question
A ball is projected from ground level at 40 m/s at 30° above the horizontal. Find the maximum height and range. Take g = 10 m/s².
Step-by-step solution
- Vertical component:
u_y = 40 sin 30° = 20 m/s - Max height:
H = u_y²/(2g) = 400/20 = 20 m - Time of flight:
T = 2u_y/g = 4 s - Range:
R = u_x · T = (40 cos 30°)(4) ≈ 138.6 m

AP Mathematics · Chain rule & differentiation
Problem. Find d/dx [(3x² + 1)⁵].
- 1
Step 1 — State the function and goal
Given f(x) = (3x² + 1)⁵, find f′(x) using the chain rule (AP Calculus AB/BC).
- 2
Step 2 — Introduce inner function u(x)
Let u = 3x² + 1. Then f(x) = u⁵.
u = 3x² + 1 → f = u⁵ - 3
Step 3 — Differentiate the outer function
Power rule on u⁵ with respect to u:
df/du = 5u⁴ - 4
Step 4 — Differentiate the inner function
Differentiate u = 3x² + 1 with respect to x:
du/dx = 6x - 5
Step 5 — Apply the chain rule
Combine: f′(x) = (df/du)(du/dx).
f′(x) = 5u⁴ · 6x - 6
Step 6 — Substitute u back in terms of x
Replace u with 3x² + 1 and simplify the coefficient.
f′(x) = 30x(3x² + 1)⁴
Final answer
f′(x) = 30x(3x² + 1)⁴

“I used to spend all night on mechanics in Physics. The step-by-step working is exactly how my teacher marks — I cleared SS3 first term comfortably.”
Chioma O.
SS3 · Lagos
“JAMB Maths under pressure was my fear. I paste past questions here and get full solutions in minutes. My score moved from 48 to 61 in practice mocks.”
Ibrahim M.
UTME candidate · Kano
“WAEC Further Maths nearly finished me. This platform shows every line of algebra; I could explain it back in class without cramming.”
Damilare T.
SS3 · Ibadan
“200-level stats module — I upload PDFs from the lecturer and get worked examples I can submit as study notes. Saved my carry-over story.”
Ngozi E.
Unilorin · Statistics
“HND Electrical — the solver handles Laplace and circuit questions with units shown. My supervisor even asked where I got the neat workings.”
Kelvin A.
Polytechnic · South-South
“Chapter 2 of my thesis was stuck for weeks. The composer broke literature review into sections and suggested APA citations I could verify.”

Frequently asked questions
Everything you need to know before you start your subscription.
We optimise for Nigerian secondary exams (WAEC, NECO, GCE), JAMB/UTME, and common university and polytechnic modules. You can still ask general questions — the AI uses your selected subject and level as context.
New accounts get 3 free AI solutions after registration — no payment needed. Full history, file uploads, and thesis tools unlock with an active monthly plan.
Plans are billed monthly in NGN. At launch we support Paystack and local bank transfer — your account activates after payment confirmation.
Yes. Signed-in users get encrypted task history so you can revisit solutions and download them again. Similar past tasks help the model suggest related practice — we never share your personal worksheets publicly.
The thesis composer drafts structure and wording you should review and cite properly. Use it as a guide; verify sources and follow your department’s plagiarism policy.
Images (PNG, JPG), PDFs, and typed text. Large files or blurry scans may need a retake — the scanner UI will prompt you when quality is low.
