Clear & precise, brought into clarity & understanding what i could not gain from the Text book! Well done!
It's a great video, i wish to download.
I could download one video, that's wy I
bought this one.
The actual word problems were kind of silly dealing with kites and whatnot but the math was solid and bringing it all together from the problem was helpful.
The teacher person has a monotone voice but following along with or without sound is actually very easy. So if you need trig practice I found it helpful.
