You can put this solution on YOUR website!
looks like calculus.
\n" ); document.write( "i didn't see a category for calculus.
\n" ); document.write( "i put it in evaluation of expressions because this is an expression and you are evaluating it by finding the derivative.
\n" ); document.write( "might be a stretch, that was my best guess.
\n" ); document.write( "i don't remember a lot about calculus, but i do remember the rules are:
\n" ); document.write( "derivative of ax^n equals n * a * x^(n-1)
\n" ); document.write( "a is the coefficient.
\n" ); document.write( "x is the variable.
\n" ); document.write( "using those rules, i would say the derivative of x^2 - 3x + 1/x would be calculated as follows:
\n" ); document.write( "rewrite the equation as the equivalent expression of:
\n" ); document.write( "x^2 - 3x + 1x^(-1)
\n" ); document.write( "take the derivative following the rules to get:
\n" ); document.write( "2x - 3 - 1x^(-2) which results in:
\n" ); document.write( "2x - 3 - 1/x^2 which can be rewritten as:
\n" ); document.write( "2x - 1/x^2 - 3
\n" ); document.write( "i found a calculator on the web that differentiates equations.
\n" ); document.write( "that calculator can be found at:
\n" ); document.write( "http://freemathhelp.com/derivative-calculator.php?diff=x^2-3*x%2B1%2Fx&var=x&Submit=Get+Derivative
\n" ); document.write( "it gave me the same answer.
\n" ); document.write( "i believe this calculator needs you to explicitly enter multiplication operators.
\n" ); document.write( "your equation of x^2 - 3x + 1/x should be entered as:
\n" ); document.write( "x^2 - 3*x + 1/x
\n" ); document.write( "
\n" );
