Hi /sci/
I'm looking to try and line up an apprenticeship in carpentry about mid next year. I have an intermediate knowledge of maths (addition, subtraction, multiplication, division and square measurements). I know geometry and trigonometry are two that would be important to know and I'm confident its not to late to learn these things properly, so could any of you please recommend some good textbook or references?

geometry + trig an absolute must. How do you even do calculations with angles?
A step further would be multivariable calculus to study volumes. A think mech eng or civil eng programme would be best for you anon.

Study what they call "college algebra" and trigonometry. I recommend the book Algebra and Trigonometry by Swokowski and Cole. Older editions are great and can be gotten for $15 or so. This is what I used to get back into math at the age of 21. And I now have an MS in mechanical engineering.
