📐 Basic Derivative Rules

These fundamental derivative formulas are the foundation of differential calculus.

Rule Name Formula Example
Constant Rule d/dx[c] = 0 d/dx[5] = 0
Power Rule d/dx[x^n] = n·x^(n-1) d/dx[x³] = 3x²
Constant Multiple d/dx[c·f] = c·f' d/dx[5x²] = 10x
Sum Rule d/dx[f + g] = f' + g' d/dx[x² + x³] = 2x + 3x²
Difference Rule d/dx[f - g] = f' - g' d/dx[x³ - 2x] = 3x² - 2
💡 Power Rule Tip

The power rule works for all real numbers n, including negative and fractional exponents! For example: d/dx[x^(-2)] = -2x^(-3) and d/dx[√x] = d/dx[x^(1/2)] = (1/2)x^(-1/2)

⚡ Advanced Derivative Rules

These rules handle more complex scenarios involving products, quotients, and composite functions.

Rule Name Formula Example
Product Rule d/dx[f·g] = f'·g + f·g' d/dx[x²·sin(x)] = 2x·sin(x) + x²·cos(x)
Quotient Rule d/dx[f/g] = (f'·g - f·g')/g² d/dx[x/sin(x)] = (sin(x) - x·cos(x))/sin²(x)
Chain Rule d/dx[f(g(x))] = f'(g(x))·g'(x) d/dx[sin(x²)] = cos(x²)·2x
⚠️ Common Mistakes
  • Product Rule: d/dx[f·g] ≠ f'·g' (You MUST use f'g + fg')
  • Quotient Rule: Remember the order! It's (low d-high minus high d-low) / low²
  • Chain Rule: Don't forget to multiply by the inner derivative!

📊 Trigonometric Derivatives

Trigonometric function derivatives are essential for calculus and physics applications.

Function Derivative Notes
sin(x) cos(x) Most common trig derivative
cos(x) -sin(x) Note the negative sign!
tan(x) sec²(x) Also equals 1 + tan²(x)
cot(x) -csc²(x) Negative of csc²(x)
sec(x) sec(x)·tan(x) Product of function and tan
csc(x) -csc(x)·cot(x) Negative product
💡 Memory Aid

For co-functions (cos, cot, csc), the derivative has a negative sign. Regular trig functions (sin, tan, sec) have positive derivatives!

🔢 Exponential & Logarithmic Derivatives

Exponential and logarithmic derivatives are crucial for growth, decay, and optimization problems.

Function Derivative Notes
e^x e^x Derivative equals itself!
a^x a^x·ln(a) For any constant base a > 0
ln(x) 1/x Natural logarithm
log_a(x) 1/(x·ln(a)) Logarithm base a
ln|x| 1/x Works for x < 0 too
💡 e^x Special Property

The function e^x is unique because it's the only function that equals its own derivative! This makes it incredibly important in differential equations.

🔄 Inverse Trigonometric Derivatives

Inverse trig derivatives appear in integration and arc length problems.

Function Derivative Domain
arcsin(x) or sin⁻¹(x) 1/√(1 - x²) -1 < x < 1
arccos(x) or cos⁻¹(x) -1/√(1 - x²) -1 < x < 1
arctan(x) or tan⁻¹(x) 1/(1 + x²) All real x
arccot(x) or cot⁻¹(x) -1/(1 + x²) All real x
arcsec(x) or sec⁻¹(x) 1/(|x|√(x² - 1)) |x| > 1
arccsc(x) or csc⁻¹(x) -1/(|x|√(x² - 1)) |x| > 1

🌊 Hyperbolic Function Derivatives

Hyperbolic derivatives are used in engineering, physics, and special relativity.

Function Derivative Notes
sinh(x) cosh(x) Similar to sin → cos
cosh(x) sinh(x) NO negative sign!
tanh(x) sech²(x) Like tan → sec²
coth(x) -csch²(x) Negative version
sech(x) -sech(x)·tanh(x) Negative product
csch(x) -csch(x)·coth(x) Negative product
💡 Hyperbolic vs Trig

Notice how hyperbolic derivatives are similar to trig derivatives, but with key differences. The derivative of cosh(x) is sinh(x) with NO negative sign, unlike cos(x) → -sin(x)!
