Math
Exponents, roots, trigonometry, and logarithms — type an expression or use the buttons.
Trig functions (sin, cos, tan) take degrees.
Calculating the hypotenuse-adjacent relationship in a right triangle with a 30° angle: cos(30) returns approximately 0.866 directly, no need to convert to radians first since this calculator works in degrees by default — matching how the angle is usually given in real problems rather than requiring a manual π/180 conversion.
A dedicated scientific calculator app or device isn't always at hand, but a browser is — and this calculator supports typing full expressions with proper order of operations, not just single-button-at-a-time entry, which makes multi-step calculations faster to enter correctly.
Degrees. sin(90) returns 1, matching what most people expect from a standard calculator, rather than requiring radian conversion.
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 ).
Yes — click into the display and type your expression, then press Enter. The buttons are there for convenience, especially for functions and constants.
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.
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).
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.
