Rules of TCS iON GATE Virtual Calculator
- Post-fix Operation: For functions like sin, cos, ln, sqrt, enter the value first, then click the function.
- No Parenthesis Keys on Keyboard in Exam: In actual exam hall mouse clicks are used; practice using memory keys (MS, MR) for complex nested expressions.
- Trigonometric Angle Modes: Check whether Deg or Rad is selected before evaluating trig functions like sin(x) or atan(x).
- Modulus Operation: Use the
modkey for integer remainder calculations.
5 Mistakes That Cost Marks in GATE
- Forgetting Deg/Rad Mode: Solving trig questions in Radian mode when degrees were expected (e.g. sin 30).
- Confusing log and ln:
logis Base-10, whereaslnis Natural Log (Base-e). - Incorrect Precedence: Expecting standard BODMAS without explicit parentheses or intermediate memory storage.
- Not Clearing Memory: Failing to press
MCbefore starting a new memory storage sequence. - Inverse Trig Errors: Using regular sin instead of
sin-1for arcsin calculations.
Frequently Asked Questions (FAQ)
Q. Is a physical scientific calculator allowed in the GATE exam?
No, physical calculators are strictly prohibited in the GATE exam hall. Candidates are only allowed to use the official on-screen TCS iON Virtual Calculator provided on their exam computer terminal.
Q. How do scientific functions (sin, cos, log, sqrt) work in the GATE virtual calculator?
The GATE virtual calculator operates on post-fix notation for unary operators. You must enter the number first, then click the function button. For example, to calculate sin(30°), type '30' and then click 'sin'.
Q. What is the difference between Deg and Rad mode in GATE Virtual Calculator?
Deg (Degrees) calculates trigonometric functions using degrees (e.g. sin(90) = 1). Rad (Radians) calculates using radians (e.g. sin(π/2) = 1). Always verify the selected radio button before solving trigonometric questions in GATE.
Q. How do memory keys (MS, MR, MC, M+, M-) function in the GATE calculator?
MS stores the displayed value into memory. MR recalls the memory value to display. MC clears memory to zero. M+ adds displayed value to memory, and M- subtracts displayed value from memory.
Q. Can I use desktop keyboard shortcuts during online practice on GateTogether?
Yes! On GateTogether's GATE Virtual Calculator, you can use digit keys (0-9), basic operators (+, -, *, /), Enter for =, Backspace to erase, and Escape to clear (C), speeding up calculation practice.
