Hi Mr. Dycho-Do you have any way to help me solve the general problems; I'm stuck on #69.
Thanks

Hello,

General problems are harder, so naturally we are confused on those more than the regular ones.

Thanks

Hi bobyang,

Yes, I would agree that the general problems are a bit harder, although the rated questions are assigned more commonly since the teacher will have an idea for how difficult their homework assignment is. I think general problems are a bit more difficult because they tend to draw on several chapter topics at once, rather than being pinned down to a specific section. Hopefully the advice I wrote above about finding one or more similar questions that I have posted videos for will be helpful. Keep in mind that the effort to figure things out on your own is an important part of the learning process.

Best wishes,
Mr. Dychko

Hi dorfte, well, I called it done after recording for 3.5 years, and 1674 videos. I don't have plans to do any of the 'general problems'. What I can suggest, however, is maybe searching for a similar problem among the ones I've answered, and seeing if the same problem solving technique might apply to #69? Good luck.
