Study Notes
Vectors in Mathematics
- A vector is a mathematical object with both magnitude and direction.
Vector Operations
- When two vectors are added together, their corresponding components are added separately.
Vector Quantities
- Examples of vector quantities include displacement, velocity, and acceleration.
Binomial Theorem for Positive Integer Indices
- The binomial theorem is a formula for the expansion of powers of a binomial.
Binomial Expansions
- $(a + b)^2 = a^2 + 2ab + b^2$
- $(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3$
- $(a + b)^4 = a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4$
- $(a + b)^5 = a^5 + 5a^4b + 10a^3b^2 + 10a^2b^3 + 5ab^4 + b^5$
