Sanjay Ghodawat International School, Kolhapur Interview Questions, Process, and Tips

A polynomial is an expression consisting of variables, coefficients, and exponents that can be added, subtracted, and multiplied.

• Polynomials can have one or more terms, with each term consisting of a coefficient, variable(s), and exponent(s).

• The degree of a polynomial is the highest exponent of the variable in the expression.

• Examples of polynomials include: 3x^2 + 2x - 5, 4y^3 - 7y^2 + 2y + 1, and 2x^4 - x^2 + 3.

Trigonometric identities are true all the time due to their mathematical properties and definitions.

• Trigonometric identities are based on the definitions of trigonometric functions and their relationships.

• They are derived from basic trigonometric ratios and properties such as Pythagorean theorem.

• Examples include sin^2(x) + cos^2(x) = 1 and tan(x) = sin(x)/cos(x), which hold true for all values of x.
