@ejsg34 it actually looks like the mistake is in the question itself. He writes tan(x^4) by mistake and then unknowingly makes the correction tan(x^3) in the second line because he's so used to doing similar problems.

08:04 1/x.... isnt it just logx???

Hello Patric,
I`m sorry but I think you made a mistake by writing tan(x^4) to tan(x^3) in second line.

I love your videos! I am wondering, are you using Stewart Calculus 6th edition? Because some of the problems are exact copies ( which is awesome because we are using this book for the semester).

I cannot thank you enough for these videos. You just saved me from getting an F on my calculus test tomorrow. :)

in this video, in the first example you do the chain rule to get sec^2(x^3)(3x^2)
how come you dont do the product rule to get sec^2(x^3)+ tan(3x^2)???

@stellar987654321 cause tan(x^3) is a composition and not a product. if it was [tan(x)] (x^3), THEN you would use the product rule. this is why teachers get upset if one just writes sin or cos... it does not mean anything.
