SALIENT FEATURES of SCIENTIFIC CALCULATOR 
 
? 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. For example, ‘sininv’ is placed below ‘sin’ 
? Hyperbolic functions are grouped together. 
? 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. 
 
Frequently Asked Questions 
PLEASE NOTE THAT THE GATE2016 QUESTION PAPERS WILL BE SET CONSIDERING THE USAGE OF ONLINE 
CALCULATOR. ALL THE NECESSARY FUNCTIONS AND OPERATIONS HAVE BEEN PROVIDED. ANY CALCULATIONS 
NEEDED FOR SOLVING THE QUESTIONS CAN BE CARRIED OUT USING THIS CALCULATOR. 
 
1) No option is available for calculations involving fractions. Why? 
This is not a fractional calculator. NAT questions needs the answers only in decimal form. 
2) How to convert polar to rectangular form and vice versa? 
No separate keys are available for this. Candidates are expected to use appropriate conversions using the 
calculator. 
3) How to represent Complex numbers? 
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. 
4) How to carry out Matrix operations like inverse, transpose etc? 
Matrices of numbers cannot be represented. The candidates need to carry out all the matrix related 
calculations manually. 
5) How to solve quadratic, cubic or simultaneous equations? 
This is a non-programmable calculator. It does not solve equations. 
6) Can I get a stand-alone calculator app for mobile or computer? 
No. Please access the calculator through web. Web connection is needed only to load the calculator on your 
webpage on your computer or mobile. Once it is loaded you do not need internet connection to carry out the 
calculations.

7) How to access the values of constants like Planck’s constant, electron mass etc.? 
Any constants needed for solution will be provided in the question paper. Wherever it is not provided then it 
is expected that the candidates should know the values of the constants. 
8) Can I use the keyboard? 
No, Keyboard will not be accessible during the entire duration of examination. Please use mouse. 
9) How do I Evaluate 4root16 ? 
The key sequence is 16, yrootx, 4. Please note that the top display area is showing the sequence of the keys 
pressed and not the formula.
