Derivative Practice 11 Names: Math& 151 Find the derivative of the following functions: 1. f(x) = sin(x) + x" 2. f(x) = (4x 5)(x2 4x +3) 3. f(x) = (3x2 4x + 11)Cos(x) 4. f(x) = (x3 +3):2 +2x+ 9Xx'3 +x'2 +351) 5. f (x) = x3tan(x) 6. f (x ) =: sin(x) x2 7. Use the quotient rule to find the derivative of f (x) = cot(x) 8. Find the equation for the line tangent to y = (x2 - 2x + 3)cos(x) at x = 0
