Study Notes
Set Operations
- 𝐸 = {47, 48, 49, 50} and 𝐹 = {48, 50, 49, 47} are two sets.
- The intersection of two sets, denoted by ∩, contains elements common to both sets.
- Hence, 𝐸 ∩ 𝐹 = {47, 48, 49, 50} = 𝐸 = 𝐹, since both sets contain the same elements.
Complex Numbers
- The conjugate of a complex number is obtained by changing the sign of the imaginary part.
- The conjugate of (1 − 𝑖)(3𝑖 + 2) can be found by applying the distributive property and then changing the sign of the imaginary part.
Polynomials
- A polynomial is an expression consisting of variables (such as 𝑥 or 𝑦) and coefficients (such as numbers) combined using only addition, subtraction, and multiplication.
- The terms of a polynomial are separated by PLUS signs, and each term contains a variable raised to a non-negative integer power.
