Vedclass · Answer

(D) The integral is $\int_{-2}^{2.24} [x] \, dx$. We split the interval based on the jumps of the greatest integer function $[x]$:
$\int_{-2}^{2.24} [x] \, dx = \int_{-2}^{-1} -2 \, dx + \int_{-1}^{0} -1 \, dx + \int_{0}^{1} 0 \, dx + \int_{1}^{2} 1 \, dx + \int_{2}^{2.24} 2 \, dx$
Evaluating each part:
$\int_{-2}^{-1} -2 \, dx = -2[-1 - (-2)] = -2(1) = -2$
$\int_{-1}^{0} -1 \, dx = -1[0 - (-1)] = -1(1) = -1$
$\int_{0}^{1} 0 \, dx = 0$
$\int_{1}^{2} 1 \, dx = 1[2 - 1] = 1$
$\int_{2}^{2.24} 2 \, dx = 2[2.24 - 2] = 2(0.24) = 0.48$
Summing these values: $-2 - 1 + 0 + 1 + 0.48 = -2 + 0.48 = -1.52$.
Note: Since the provided options do not match the calculated result,the correct value is $-1.52$.

Evaluate the definite integral $\int_{-2}^{2.24} [x] \, dx$,where $[x]$ denotes the greatest integer function.
