I would like to see a College Algebra forum. It is a course at Lehman College that gives students lots of trouble. At Lehman, the course is known as MA104.
 
Physics news on Phys.org
It's a good suggestion, though I took its equivalent in High School, not College. (Not an AP course.)

MAT 104 College Algebra
Rational expressions, integer and rational exponents, quadratic formula, complex numbers, exponential and logarithmic functions, conic sections, trigonometry. Mathematics laboratory attendance may be assigned at the discretion of the instructor.
I think they all fit in the forums that already exist as https://mathhelpboards.com/trigonometry-12/ already has its own forum and the rest:

Rational expressions, integer and rational exponents, quadratic formula $\to $ https://mathhelpboards.com/pre-algebra-algebra-2/

Complex numbers, exponential and logarithmic functions, conic sections $\to$ https://mathhelpboards.com/trigonometry-12/
Some of those topics may fit either forum in any case. Someone correct me if this doesn't sound right.
 
Thread 'How to define a vector field?'
Hello! In one book I saw that function ##V## of 3 variables ##V_x, V_y, V_z## (vector field in 3D) can be decomposed in a Taylor series without higher-order terms (partial derivative of second power and higher) at point ##(0,0,0)## such way: I think so: higher-order terms can be neglected because partial derivative of second power and higher are equal to 0. Is this true? And how to define vector field correctly for this case? (In the book I found nothing and my attempt was wrong...
