Detailed Solution

Concept: Those used for mathematical calculations, especially small electronic devices with keyboards and visual displays, are called calculators. Calculators can perform different functions depending on the reason for your purchase. Some calculators can display the values of trigonometric functions, some can be used to get simple or compound interest, and some can be used to plot a graph for a particular function.
Scientific Calculator-A scientific calculator is a kind of electronic calculator, usually, but not always, portable and designed to calculate scientific, engineering and maths problems. They completely replace the slide rule of traditional applications and are widely used in both educational and professional settings. Modern scientific calculators generally have many features, including:
1. Scientific Notation
2. Floating point arithmetic
3. logarithmic functions, using both base 10 and base e
4. trigonometric functions
5. exponential functions and roots beyond the square root
6. quick access to constants such as π and e.
Financial Calculator – A financial calculator or business calculator is a calculator that performs the financial functions commonly needed in the business and trading community, such as simple interest, compound interest, cash flow, amortisation, conversion, costs / sales / margins, etc. is. There are many financial and function-specific keys that make such calculations more direct than standard calculators. Because it is user-programmable, users can add features not provided by the manufacturer by default.
Graphing Calculator-A graphing calculator (also known as a graphing calculator or graphic display calculator) is a handheld computer that can perform other tasks, including drawing graphs, solving simultaneous equations, and variables. The most popular graphing calculators are also programmable, so they are considered programmable calculators, and users can usually create custom programs for scientific, engineering, and educational applications. Due to the larger display compared to traditional 4-function calculators, graphing calculators typically display multiple lines of text and calculations at once.
Hence, the correct answer is option (4).
