Formula & How It Works
sin(30) [DEG] = 0.5 · 2^10 = 1024 · log(1000) = 3
- The keypad builds one full expression and evaluates it with operator precedence, so multiplication happens before addition: 2 + 3 × 4 is 14, not 20.
- Trigonometry follows the DEG/RAD switch, and log is base 10 while ln is base e.
- Powers (^), square roots and parentheses are all available, so nested expressions can be evaluated in a single pass.
Step-by-Step Example
Three quick checks you can run on the keypad.
- 1.Trigonometry
- sin(30) with the DEG switch on
- 2.Powers
- 2^10
- 3.Logarithm
- log(1000), the base-10 log
sin(30) = 0.5, 2^10 = 1024, and log(1000) = 3.
Frequently asked questions
Does this scientific calculator support radians and degrees?
Yes. The DEG/RAD switch decides how trigonometry is interpreted: in DEG mode sin(30) is 0.5, and in RAD mode the same input is read as radians, which gives −0.988. Keep it on DEG for school, surveying and navigation work, and on RAD for calculus and physics.
How do I calculate powers and square roots on this calculator?
Use ^ for powers — 2^10 evaluates to 1024 — and the √ key for square roots, where √9 gives 3. Because it evaluates a whole expression rather than a running total, it respects operator precedence, so 2 + 3 × 4 is 14, and parentheses let you group terms when you need to override that order.
Can I use standard keyboard shortcuts for input?
Yes. Numbers, + − × ÷, parentheses, ^ and Enter all work from the keyboard, with Backspace for delete and Escape to clear the current expression. That makes it usable from a numeric keypad or a laptop keyboard without reaching for the mouse.
