Let $$style{fоnt-size:18pt}{A}$$ be the net signed аreа under the curve $$style{fоnt-size:18pt}{y=x^2}$$ оn the intervаl $$style{font-size:18pt}{1le xle 3.}$$ (a) Use a definite integral to calculate the area $$style{font-size:18pt}{A}.$$ (b) Use the limit definition of the definite integral to calculate the area $$style{font-size:18pt}{A}.$$Recall that we defined the definite integral as $$style{font-size:18pt}{int_a^b f(x) dx = lim_{nrightarrow infty} sum_{i=1}^{n} f(x_i) Delta x .}$$The following formulae may be useful:$$style{font-size:18pt}{sum_{i=1}^{n} 1 = 1+ 1 + 1+ dots + 1 = n}$$$$style{font-size:18pt}{sum_{i=1}^{n} i = 1+ 2 + 3+ dots + n = dfrac{n(n+1)}{2}}$$$$style{font-size:18pt}{sum_{i=1}^{n} i^2 = 1^2+2^2+3^2+dots+n^2 = dfrac{n(n+1)(2n+1)}{6}.}$$
