Sine/Cosine wave oscillator by TL082

I introduce the oscillator which outputs the Sine wave and the Cosine wave at the same time using the operational amplifier. Because the distortion was big at the circuit to have been introducing before, I improved at the circuit with little distortion. The circuit this time combines the integration circuit and the inverter by the operational amplifier.
