- ugh 16y agoHardly. You can just type it into WolframAlpha, that works perfectly. (Which is quite funny because you are letting the computer solve something that’s supposed to keep computers out.) You don’t even need to learn any fancy syntax, “derivative of” works great. (High school math homework would be so much easier with WolframAlpha.)
