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.
