lnx 1/x The expression lnx can be simplified as the natural logarithm of the variable x. The natural logarithm is a function that takes the logarithm of...
quotient rule g(x)f'(x)-f(x)g'(x)/g(x)^2 Quotient rule is a formula used in calculus to find the derivative of the quotient of two functions, which represents the rate at which...
chain rule f'(g(x))g'(x) The chain rule is a formula used in calculus to find the derivative of a composite function. A composite function is a function that...
derivative of tan(x) sec^2(x) The derivative of tan(x) can be found using the quotient rule, since tan(x) can be written as sin(x)/cos(x): f(x) = sin(x) g(x) =...
derivative of sin(x) cos(x) The derivative of sin(x) is cos(x). We can prove this by using the definition of the derivative: f'(x) = lim Δx→0 [f(x+Δx) –...
