Students mostly practice with their personal scientific calculator during their college academics as well as for GATE examinations. However, this practice has been taken to another by IISc Bangalore by Not allowing personal scientific calculator in the GATE 2016 examination, however provided another valuable route to perform calculations in the name of “Virtual Scientific Calculator”. Since GATE 2016 students are requested to practice in Virtual Online Scientific Calculator instead of the personal scientific calci.

Advantages of Using Virtual Scientific Calculator for GATE:

As peoples are finding difficulties in shifting to the usage of Online Scientific Calculator than the normal personal scientific calci, there are various advantages associated with usage of Online Virtual Calculator in GATE and are as follows.

  • For easy access, the right hand side of the virtual calculator contains all the keys required for simple operations.
  • All Scientific functions and operations are separated on the left hand side of the virtual calculator.
  • Inverse functions have separate keys (no need to press SHIFT or INV keys)
  • Functions are grouped together for easy access. All trigonometric functions are together. Inverse functions are placed below the respective functions.
  • Two display boxes are provided at the top of the virtual calculator. The top box indicates the sequence of the keys pressed (not the actual calculations) and is just for reference.
  • The display box below it indicates the actual values entered or obtained after calculations.

FAQs about using GATE 2017 Virtual Calculator:

Some FAQs about the GATE 2017 Virtual Scientific Calculator are as follows

Q: How to do the calculations involving fractions?

A: This is not a fractional calculator. NAT questions need answers only in decimal form.

Q: How to convert polar to rectangular form and vice versa?

A: Candidates are expected to use appropriate conversions using the calculator as no separate keys are available for this.

Q:  How to represent Complex numbers?

A: Complex numbers cannot be represented in this calculator. All questions relating to any area where complex numbers might be deemed useful, eg. in power systems or other areas, can be solved using this calculator.

Q:  How to carry out Matrix operations like inverse, transpose etc?

A: Candidates need to carry out all the matrix related calculations manually.

Q:  How to solve quadratic, cubic or simultaneous equations?

A: The GATE 2017 Virtual Calculator is a non-programmable calculator. It does not solve equations.

Q: Can one get a stand-alone calculator app for their mobile or computer?

A: No. The calculator can be accessed through web. A Web connection is needed only to load the calculator on your webpage on your computer or mobile. Once it is loaded an internet connection is not needed to carry out the calculations.

Q: How to access the values of constants like Planck’s constant, electron mass etc.?

A: The constants needed for solving any questions will be provided in the question paper. Wherever it is not provided then it is expected that the candidates should know the values of such constants.

Q: Can a student use the keyboard?

A: No. students cannot access the keyboard during the entire duration of examination. They will have to use the mouse only.

Q: How to evaluate 4root16?

A: The key sequence is 16, yrootx, 4. Students must remember that the top most display area will show the sequence of the keys pressed and not the formula.
