Difficult to understand and kept bugging me to install the pro version for very basic opamp calculations, cannot recommend to anyone

For an inverting amplifier, there are 4 variables vi, vo, r1, rf. Select an item you want to find (e.g. Vo). Input other three variables . Vo will be calculated. If you still have problems using the app, please send me an email
