Integration using the power rule
Nettetthe power is a fraction, this means that the function will have an x under a root like f ( x) = 5 x . We start by learning the formula for the power rule . Power Rule Given a function which is a power of x, f ( x) = a x n, its derivative can be calculated with the power rule: if f ( x) = a x n then f ′ ( x) = n × a x n − 1 We can also write this:

To do that, we let u = x u = x and dv=\cos (x) \,dx dv = cos(x)dx: \displaystyle\int x\cos (x)\,dx=\int u\,dv ∫ xcos(x)dx = ∫ udv u=x u = x means that du = dx du = dx.
NettetObjectives. Students will be able to. understand what a definite integral is and how it differs from an indefinite integral, evaluate definite integrals that can be integrated using the power rule, find algebraic constants by evaluating definite integrals, solve real-world problems involving definite integrals. NettetBecause this equation only consists of terms added together, you can integrate them separately and add the results, giving us: #int x^3 + 4x^2 + 5dx = intx^3dx + int4x^2dx + int5dx# Each of these terms can be integrated using the Power Rule for integration, which is: #int x^ndx = x^(n+1)/(n+1) + C#. Plugging our 3 terms into this formula, we have:
NettetThe power rule in calculus is a fairly simple rule that helps you find the derivative of a variable raised to a power, such as: x ^5, 2 x ^8, 3 x ^ (-3) or 5 x ^ (1/2).
