I have no resources, sorry. But I would suggest that if you had trouble in hs math, you may find it beneficial to go back to jr high math. Maybe. Geometry less so. But trig depends on good algebraic skills.

BTW, I have a hazy and possibly erroneous impression that all the best math instruction is by video these days, because it really is superior to learning it from a book. You may want to give Khan Academy a try despite your issues with video.
