    i have no idea how to build a circuit which will indicate if the wave is a sine wave or square wave or triangular wave....i cannot use micro-controllers and oscilloscope....any ideas would be welcome....:)
    Thanks in advance......

    An FFT (Fast Fourier Transform) of each equation will let you know the general "shape" it would have on a scope.

    --ETA: Hint One method to do it, unsure how complicated your instructor would like though.

    Integrate square wave for a triangle wave. Integrate a triangle wave for a sine wave.

    Differentiation reverses the process.
