answerFriends, asking for a little help. Can you please recommend a good English textbooks on algebra and mathematical analysis, which would have covered the knowledge from the very basics, because I feel the lack of fundamental knowledge in this area.
At the moment, I found a few books with a good rating:
1. College Algebra, by...

By education I am a humanist, although in high school algebra were given to me relatively easily.
I decided to educate myself and pass some courses in Coursera and EDX.
Very interested in the opportunity to implement techniques predlagaemye to the result based on the quantification (counting). As I understood, my pra...

answersThere are different graphs, but we are talking about those that are in the set of arithmetic operations and trigonometric functions.
Now, suppose the user enters the formula. The chart thus may not cross the axes (for example: k/x), can cross many times OX, intersecting the OY (example: ctg(x)). Plus, the added offset using...

answersI think I can not understand . If we have a basis of 4-dimensional space have the right to say that if we have a 3-dimensional subspace we can Express any 3-dimensional vector using the basis of our 4-dimensional space ? (like if the 4-coordinate 0 , it's still a vector 3-dimensional space ?)

answersThere is y whose value is dependent on two arguments x and z
x is any number
z - number is either negative or positive
If z>0 then y is positive
If z<0 then the sign of y is determined by the sign x.
