**Before you can use** **face mill inserts****, you need to learn the basics of engineering. This field requires a solid understanding of complex mathematical principles and the ability to solve high-level equations. Of course, you’re not expected to do everything from scratch. In fact, there’s a special calculator that can help you in your engineering studies and work.**

**What Is an Engineering Calculator?**

**An engineering calculator can perform basic arithmetic just like a standard calculator, but it can also perform more complex functions:**

- Find the line of best fit
- Calculate the area under a curve
- Graph cosine and sine functions
- Solve for variables in the Quadratic formula
- Calculate the volume of 3D shapes

Most engineering calculators have square screens where you can type in equations. Depending on the function, you can also view graphs.

**What Is an Engineering Calculator Used For?**

**Also called graphing calculators, engineering calculators are required for higher-level math classes as well as applied-math sciences such as engineering and physics. Before the widespread use of these tools, students and professionals had to either do this complex math by hand or consult a cumbersome tool called a slide rule. Today, engineering calculators do the mundane work to cut down on wasted time and human error.**

**Trigonometry**

**Trigonometry is a subject studied in pre-calculus classes. Its purpose is to determine angles, and it’s critical to the following fields:**

- Surveying
- Astronomy
- Mapmaking

**Logarithms**

**Logarithms show up in many surprising places:**

- Music
- Art
- Nature

Of course, they’re also used in applied sciences such as chemistry. What do they do? Logarithms help you determine the base of a number and how many times that base gets squared to achieve the original figure.

**What Should You Look for When Shopping for an Engineering Calculator?**

**Since there are so many models out there, finding the right** **engineering calculator**** can take time. How can you tell which you should buy? Here are three factors to consider.**

**Affordable Price**

**Graphing calculators can get extremely expensive, but just because something is pricey doesn’t mean it’s the best. As you look at calculators, save yourself some money by checking the cost. There may be another model that does the same thing but is much cheaper.**

**Testing Policies**

**You may need an engineering calculator for tests. You should consult the institution’s testing policy before purchasing a model, as you may not be able to use your calculator if it’s not on the approved list. In the worst-case scenario, you may not be allowed to take the test at all.**

**Appropriate for Your Work**

**Finally, you should find a calculator that suits your immediate computing needs. For example, you don’t need a calculator designed for professional engineers if you’re a high school student. While the more complex models may seem better, you’ll end up paying for functions you never use. **

**Now that you know what to look for, you’re sure to find the perfect calculator for your needs. With its help, you can tackle the questions necessary to build bridges and design machines. In fact, you’ll be on your way to using** **Kennametal end mills**** in no time.**
