WebThe following steps would be useful to do logarithmic derivative. Lett y = f (x) be a function in which let the variable be in exponent. Step 1 : Take logarithm on both sides. Step 2 : Apply the power rule of logarithm. Step 3 : Find the derivative and solve for dy/dx. Derivative of a to the power x. WebFeb 15, 2024 · The power rule is used to find the slope of polynomial functions and any other function that contains an exponent with a real number. In other words, it helps to take the derivative of a variable raised to a power (exponent). The Steps All we have to do is: Move the exponent down in front of the variable. Multiply it by the coefficient.
We can use the power rule to find the derivatives of functions like 1/x, ∛x, or ∛x². To do that, we first need to rewrite those functions as xⁿ, where n would be negative or a fraction.

For example, WebJan 25, 2024 · Find the derivative of f(x) = cscx + xtanx. Solution To find this derivative, we must use both the Sum Rule and the Product Rule. Using the Sum Rule, we find f′(x) = d dx(cscx) + d dx(xtanx). In the first term, d dx(cscx) = − cscxcotx, and by applying the Product Rule to the second term we obtain d dx(xtanx) = (1)(tanx) + (sec2x)(x).
WebThe following are the fundamental rules of derivatives.Let us discuss them in detail. Power Rule: By this rule, if y = x n , then dy/dx = n x n-1 .Example: d/dx (x 5) = 5x 4.. Sum/Difference Rule: The derivative process can be distributed over addition/subtraction. i.e., dy/dx [u ± v]= du/dx ± dv/dx. Product Rule: The product rule of derivatives states … WebExamples. The function () = is an antiderivative of () =, since the derivative of is , and since the derivative of a constant is zero, will have an infinite number of antiderivatives, such as , +,, etc.Thus, all the antiderivatives of can be obtained by changing the value of c in () = +, where c is an arbitrary constant known as the constant of integration. ...
