Question

Can anyone show how to get the answer of 1.69?

For the circuit below, we wish to change the frequency of oscillation from 1/(2 x R3x Cx log (3)-598.84159646502 Hz to 1/(2x R3 × C x loge(10-28 5.72005388372 Hz. Initially R1: R2+ R3 = 7.6 k ohms. What value should R3 be changed to achieve this, in k ohms to with 1% accuracy? r2 +15 V r1 15 V 00 nF r3 PS. excuse the ridiculous precision on the freq. numbers. that's not needed to get the correct answer here, anyway. Answer: 15.9288 The correct answer is: 1.69
