This scientific calculator tool lets you perform advanced mathematical calculations and graph functions directly on the web page.

## How to Use the Scientific Calculator

To use the calculator, click on the buttons to input the numbers and mathematical functions you need for your calculation. The display will show your input. Click the ‘Calculate’ button to evaluate your expression and see the result in the ‘Result’ field.

### Functions Available:

- Basic operations: addition (+), subtraction (-), multiplication (*), and division (/).
- Trigonometric functions: sine (sin), cosine (cos), and tangent (tan).
- Parentheses for grouping expressions ‘(‘, ‘)’.

### Example:

To calculate `sin(90) + cos(0)`

, input

`sin(90)`

then `+`

then `cos(0)`

and click ‘Calculate’. The result will be displayed in the ‘Result’ field.

### Limitations:

This calculator does not support advanced mathematical functions like logarithms, exponents, or handling complex numbers. Additionally, the trigonometric functions assume input in radians, not degrees. It also evaluates expressions directly using JavaScript’s `eval()`

function, which might not handle all mathematical edge cases correctly.

## Use Cases for This Calculator

### 1. Calculation Capabilities

A scientific calculator is primarily designed for performing complex scientific calculations like trigonometric functions, logarithms, and exponentials. On the other hand, a graphing calculator not only performs scientific functions but also allows you to plot graphs and analyze functions visually.

### 2. Graphing Functions

With a graphing calculator, you can input multiple equations and plot them on a graph for a visual representation. This feature helps you understand the behavior of functions and how they intersect or relate to each other. A scientific calculator doesn’t have this visual graphing capability.

### 3. Simultaneous Equations

Graphing calculators excel in solving systems of equations simultaneously. You can input multiple equations, and the calculator will find the points of intersection, providing solutions for variables. Scientific calculators can solve equations as well, but not as efficiently for complex systems.

### 4. Analyzing Data

When it comes to analyzing statistical data, a graphing calculator is the go-to device. It can calculate mean, standard deviation, regression, and more. You can input datasets and quickly generate statistical results. Scientific calculators have basic statistical functions, but graphing calculators offer more advanced analysis.

### 5. Programming Capabilities

Graphing calculators often come with programming capabilities that enable users to create custom functions and programs. This feature allows for automation of repetitive tasks and complex calculations. Scientific calculators, while powerful, lack this level of customization typically.

### 6. Financial Functions

For financial calculations like amortization, bond pricing, and cash flow analysis, graphing calculators provide dedicated functions. These are essential for students studying finance or professionals in the finance industry. Scientific calculators do not have specialized financial functions built-in.

### 7. Geometric Calculations

Graphing calculators go beyond basic geometric calculations to offer features like 3D graphing, polar graphing, and geometry applications. These functionalities are handy for students studying advanced mathematics and physics. Scientific calculators are limited in their geometric capabilities.

### 8. Data Visualization

Graphing calculators allow you to plot data points, visualize trends, and understand patterns in datasets. This graphical representation aids in making informed decisions based on data analysis. Scientific calculators lack this visual component, which can be crucial in certain fields.

### 9. Differential Equations

Graphing calculators can solve differential equations, making them invaluable for students and professionals in fields like engineering and physics. You can input differential equations and obtain solutions or plot their graphs. Scientific calculators may not have the capacity to handle differential equations efficiently.

### 10. Examination Use

In standardized tests or exams that permit calculators, a graphing calculator may be allowed due to its versatility and advanced features. It can handle a wide range of mathematical problems, giving you a competitive edge. Scientific calculators are more basic and may not be as suitable for these situations where complex calculations are required.
