Engineering Calculator
Scientific and engineering maths with trigonometry, powers, roots and logarithms.
Angle:
Examples: sin(30), sqrt(144), 2^8, log(100). Use DEG for normal angle calculations.
Engineering calculator: quick answer
An engineering calculator is useful for scientific and technical maths such as powers, roots, trigonometry and logarithms. Check the selected angle mode before using trigonometric functions.
Example
For a right-angle calculation, make sure the function and angle units match the problem before pressing calculate.
Common mistakes
- Using degrees when the problem expects radians.
- Rounding intermediate values too early.
Frequently asked questions
Why do trig answers change?
The result can change if the calculator is in degree mode instead of radian mode, or vice versa.
