Answer (1 of 2): > \int_0^\pi\dfrac{x}{a^2cos^2x+b^2sin^2x} Wolfram Alpha is not able to use any of the numerical methods to estimate the value of the definite integral, as this integral contains no numbers but arbitrary constants (a and b) If you let a=6 and b=9, then it is able to use estimat. . or substitute a value for a variable - Plot 2D or 3D functions of your choice - Determine the limit of a function as it approaches a specific value or values - Differentiate any single or . For fixed , the exponential integral is an entire function of .The sine integral and the hyperbolic sine integral are entire functions of . Use SubstitutionSystem to get its evolution over 8 iterations.

x^2+3x+4 where x=-1 X But this is tedious and unpleasant. Because Hold has the attribute HoldAll, x is not evaluated when the held expression is defined, so the body of the expression refers to the global variable x. Still, a couple of them are helpful substitutes to other WolframAlpha purposes like learning aid or direct answers to complex queries.
