KwikTrig

KwikTrig, now at its latest version 3.0.5, is an impressive tool in the Education category, specifically under Science Tools. Developed by John Fracaro, this software provides a reliable solution for solving RIGHT and OBLIQUE triangles, as well as performing detailed arithmetic for BOLT CIRCLES, SINES, and COMPOUND SINES.

Ideal for those who may not have advanced math or computer skills, KwikTrig supports various straightforward calculations. It can handle both decimal degrees and degrees/minutes/seconds for input and output, maintaining precision across all operations by rounding numbers from 1 to 15 decimal places. Additionally, KwikTrig can plot inscribed and circumscribed POLYGONS, which is a useful feature for geometry enthusiasts.

The program is available for download and supports multiple operating systems: Windows XP, 7, 8, 10, and 11. It comes in a straightforward executable file format, KwikTrig.exe. Besides the up-to-date 3.0.5 version, the older 3.0 version is also available for those who may prefer it.

KwikTrig further stands out with its geometry capabilities, allowing users to plot circles, points, and lines. The software finds intersections of these lines and can connect lines to circles at tangent points, as well as place circles tangent to angles. For those in the milling industry, KwikTrig’s SPEEDS AND FEEDS for MILLING module is particularly useful, as it remembers user input data to avoid the repetitive need to look up data each time.

One of the program's key strengths is its unit versatility, allowing data input in both INCH and METRIC units and providing seamless conversion between the two to ensure that calculations are accurate and user-friendly.

Pros:

• Comprehensive features for both basic and advanced trigonometric and geometric calculations.
• Simple for users with minimal math or computer skills.
• Supports a wide range of operating systems.
• High precision in calculations with up to 15 decimal places.
• Convenient free download option available.

Cons:

• User interface might seem outdated to those accustomed to modern design aesthetics.
• Limited to Science Tools subcategory without broader integration with other educational software.
