WebThe Derivative tells us the slope of a function at any point.. There are rules we can follow to find many derivatives.. For example: The slope of a constant value (like 3) is always 0; The slope of a line like 2x is 2, or 3x is 3 etc; and so on. Here are useful rules to help you work out the derivatives of many functions (with examples below).Note: the little mark ’ … WebDerivative examples Example #1. f (x) = x 3 +5x 2 +x+8. f ' (x) = 3x 2 +2⋅5x+1+0 = 3x 2 +10x+1 Example #2. f (x) = sin(3x 2). When applying the chain rule: f ' (x) = cos(3x 2) ⋅ [3x 2]' = cos(3x 2) ⋅ 6x Second derivative test. When the first derivative of a function is zero at point x 0.. f '(x 0) = 0. Then the second derivative at point x 0, f''(x 0), can indicate the …
