Work Step by Step
Evaluate the integral: $\int^1_0 (1 -8v^3 +16v^7) dv$
Recall the 2nd part of the Fundamental Theorem of Calculus:
$\int_a^bf(x)dx = F(b) - F(a)$
Find $F(v)$:
$F(v) = \int^1_0 (1 -8v^3 +16v^7) dv $
$F(v) =v - \frac{8}{4}v^4 +\frac{16}{8}v^8$
$F(v) =v - 2v^4 +2v^8$
Now evaluate $F(b) - F(a)$:
$F(1) - F(0)$
$(1 - 2(1)^4 +2(1)^8 )- (0 - 2(0)^4 +2(0)^8) $
$(1-2+2) - 0=1$
