So we didn't actually need to go through the last 5 lines. β«8π₯β1+π₯ π₯. 7. β«π₯. 6. β«0(1β2π₯)3 π₯. Definite vs Indefinite Integrals We previously defined the definite integral of a function f(x) between x = a and x = b: Z b n 15. 2ππ₯ βπ₯3+9 1 β1. β«0π₯β4βπ₯ π₯. With Substitute these values into the integral: β« 14(7 + 2)3 = β« 14( )3 7 Simplify the integral and integrate using the power rule: 2 β« 2( )3 = 7 β«( )3 = 4 + 4 We call this the indefinite integral. 3. One of the most powerful techniques is integration by substitution. ©L f2v0S1z3U NKYu1tPa1 TS9o3fVt7wUazrpeT CLpLbCG. Z Z cf(x) dx = c f(x) dx.
