Q. Explain Set Intersection?
Ans.
Set IntersectionSuppose your school needs to know which students are taking both art and business this year. If A is the set of students taking art and B is the set of students taking business, then the students who are taking both classes are common to A and B, or the intersection of A and B.
The intersection of two sets A and B, written A ∩ B, is the set of all elements which are common to both A and B. This can be written as.
A ∩ B = { x| x ∈ A and x ∈ B }The key word in this definition is and. The elements must be in both A and B.

Slope of Tangent Line : It is the next major interpretation of the derivative. The slope of the tangent line to f ( x ) at x = a is f ′ ( a ) . Then the tangent line is given by,
x=±4, if -2 = y =0 x=±2, if -2 = y = 0
