Step 1: Turn on your calculator. 😊
Step 2: Press SHIFT then ∫dx (the integration button)
Step 3: Enter your function.
Step 4: Press the right arrow
Step 5: Enter the x-value you want to differentiate at.
Step 6: Press =
Step 7: Read the answer.
Step 8: Check if it makes sense.
Yes, the ON button. I believe in you.
Step 2: Press SHIFT then ∫dx (the integration button)
to access d/dx (differentiation mode). Yes, the same button. It's hidden. Like your motivation.
Step 3: Enter your function.
Example: 3x² + 2x + 1
Press 3 → ALPHA → X → x² → + → 2 → ALPHA → X → + → 1
Step 4: Press the right arrow
→ to move past the function.
Step 5: Enter the x-value you want to differentiate at.
Example: x = 2
Step 6: Press =
(equals).
Step 7: Read the answer.
Write it down. That's your gradient.
Example: d/dx (3x² + 2x + 1) at x = 2
Answer: 14
Step 8: Check if it makes sense.
Does it? Or did you fat-finger a button and get 99999999? Pay attention.

So yeah, use the calculator to check. To verify. Not to replace your brain. Because the examiner won't accept "I used calculator" as working steps 😊

Think it easy. 不要紧张. Chill. Relax, not to stress YOURSELF.

If y'all get 0 marks, I'm gonna haunt your dreams with differentiation equations. Every night. Forever.
You'll close your eyes and see dy/dx. You'll dream of finding the gradient. You'll wake up screaming 'chain rule!' at 3 AM.
Integration by parts
will be your lullaby. Second derivatives will be your nightmares. And every time you see a curve,you'll hear my voice whispering: 'Find the turning point... find the turning point... 🙂

15 PERFECT SCORES (32/32): Afdzal I, Airiss, Aleesya Sofea, Cenz, Alwyn Boy, Nunu, Sixva, Akhill, Fiqahh9A+, Hafizzz, MUHAMMAD Moe, Izzati, Lanadiao, Potatomonatone, YEO CX Y.
To these 15 — RESPECT. Every question was hard (34-44% correct rate across the board). Yet you all got 100%. That didn't happen by accident; it happened because you actually studied. Well done. Keep this energy for Trial SPM.
Amsyar (31), Xy (29), Mbekk (27) — solid effort. One or two mistakes, but you're in the game. Tighten up those weak spots and you'll join the perfect club soon.
