    Study Notes

    Limits

    • The limit of a function (√x − 4)/(x − 16) as x approaches 16 is 8.
    • The limit of a function f(x) is an essential discontinuity at x = 2.
    • The left-hand limit of f(x) approaches 0, while the right-hand limit of f(x) at x = 2 approaches 2.
    • The limit of x sin (1/x) as x approaches infinity is 1, which is found by manipulating the expression and applying L'Hopital's Rule.
    • The limit of x^(1/x) as x approaches infinity is 1, which is found by manipulating the expression and applying L'Hopital's Rule.

    Differentiation

    • The derivative of a function (3√(3x^2 + x)) / √(7 - 3x) can be found using the quotient rule for derivatives.
    • The derivative of tan^4(5x^6) + Arcsec(cos x) can be found using the chain rule for derivatives.
    • The derivative of 4csc(x) log5(3x^4) can be found using the product rule for derivatives and the chain rule for derivatives.
    • The derivative of x^2 cot(x + 2y), where y is a differentiable function of x, can be found using the product rule for derivatives and the chain rule for derivatives.

    Logarithmic Differentiation

    • The derivative of y = (x sin(x)) / arccot(x) is found using logarithmic differentiation.

    L'Hopital's Rule

    • L'Hopital's rule can be used to evaluate limits of functions that have an indeterminate form of 0/0 or ∞/∞.
    • The derivative of x^(1/x) is found using L'Hopital's rule by manipulating the function into a form for which L'Hopital's rule is applicable.
