Math
Scientific Calculator
Exponents, roots, trigonometry, and logarithms — type an expression or use the buttons.
Trig functions (sin, cos, tan) take degrees.
Frequently asked questions
Are trig functions in degrees or radians?
Degrees. sin(90) returns 1, matching what most people expect from a standard calculator, rather than requiring radian conversion.
How do I calculate powers and roots?
Use the xʸ button for powers (e.g. 2 xʸ 10 = 1024) and the √ button for square roots. For other roots, use a fractional power — the cube root of 27 is 27 xʸ ( 1 / 3 ).
Can I type directly instead of using the buttons?
Yes — click into the display and type your expression, then press Enter. The buttons are there for convenience, especially for functions and constants.
How do I turn off a physical scientific calculator?
Most Casio and similar models have a dedicated "AC" or "OFF" function, often accessed by pressing SHIFT (or 2ndF) followed by AC/ON. Some models power off automatically after a few minutes of inactivity.
How do I find antilog on a scientific calculator?
Antilog is the inverse of log. On most calculators, press SHIFT (or 2ndF) then the log button, enter your value, and press equals — this computes 10 raised to that power. On this calculator, you can type the same thing directly: 10^(value).
Is a calculator allowed in competitive exams like JEE, GATE, or CAT?
This varies by exam and changes over time, so always check the exam's official guidelines close to your test date rather than relying on general information. As a general rule, JEE Main has not permitted physical calculators in recent years, while some other exams provide an on-screen calculator during the test itself.
