Question

Why is it important to study Pre-calculus?

Answer 1

Significance of study of Pre-calculus:

1. Advanced algebra and basic trigonometry are both covered in the core math subject pre-calculus.
2. Pre-calculus includes lessons on trigonometric functions, logarithms, exponents, matrices, and sequences.
3. These fundamental skills are extremely relevant to a range of real-life events, which helps us understand the relevance and utility of the content we are studying.
4. Here are some illustrations:
   1. Figure out the cost of our preferred gaming console by visiting an electronics website. Calculate the percentage that the console would need to be "on sale" for us to be able to purchase it for the pocket money possessed using logical functions.
   2. The diagonal corners of a television screen are often used to measure its size. Consider having a TV cabinet that is $\text{3 feet}$ wide and $\text{3 feet}$ height. Use trigonometry to estimate whether a $\text{42 inch}$ television that is actually $\text{24 inch}$ tall will fit into the current television cabinet.
   3. One should tally up one's collection of shirts and pants. The number of days he can go without wearing the same thing twice can be calculated using Pascal's triangle and the binomial theorem.

Hence the significance of study of Pre-calculus is explained.
