Determine the area between the x-axis, the vertical lines x = 0 and x = 1 and the following curve:\r
\n" ); document.write( "\n" ); document.write( "F(x) = 2x^3 + e^3x
\n" ); document.write( "------------------
\n" ); document.write( "\"Int+F%2B%28x%29+=+x%5E4%2F2+%2B+e%5E%283x%29%2F3\"
\n" ); document.write( "F+(1) = 1/2 + e^3/3
\n" ); document.write( "F+(0) = 1/3
\n" ); document.write( "----------
\n" ); document.write( "Area = F+(1) - F+(0) = 1/2 + e^3/3 - 1/3
\n" ); document.write( "Area =~ 6.8618 sq units
\n" ); document.write( "------------
\n" ); document.write( "F+(x) also has a C term, the constant, but they cancel when the 2 values are subtracted, so they can be ignored.
\n" ); document.write( "
\n" ); document.write( "
\n" );
