GATE 2017 will see the usage of the virtual calculator which has been the new feature incorporated from GATE 2016. The GATE exam is an online one and hence the usage of the online calculator is something that was accepted. Candidates appearing for GATE 2017 will not be allowed to carry a physical calculator to the exam hall. Instead they have to use the virtual calculator.

The fact still remains that most of the undergraduate students of engineering and technology use the physical calculators to a large extent that switching seems to become a problem. As per our survey in GATE 2016, many students found the virtual calculator cumbersome and many blamed it for bogging down their performance. The virtual calculator for GATE 2017 is given below and candidates can now use it.

**Use the GATE 2017 Virtual Calculator Below:**

**We take a look at the calculator and its features as well as how to use it for GATE 2017:**

**Important Features of the GATE 2017 Virtual Calculator**

- All the keys required for simple operations are placed on the right hand side.
- The Scientific functions and operations can be found on the left hand side
- Inverse functions have separate keys so candidates need not press SHIFT or INV keys
- All Functions are grouped together:

All Trigonometric functions are grouped together

The Inverse functions are placed below the respective functions. For example, Sin Inv is placed below Sin on the calculator

The Hyperbolic functions are also grouped together. - There are two display boxes at the top of the GATE virtual calculator.
- The top box is just for reference and will indicate the sequence of the keys pressed
- The 2nd box shows the actual values entered / values obtained after calculations

**Some examples to use the GATE Virtual Calculator:**

Calculations | Examples |

Simple Arithmetic Calculations | To calculate 60 + 35 x 3 enter 60, +, 35, *, 3, = To evaluate: 60 x 75-2 enter 60, *, 75, -, 2, = Similarly to evaluate: 25 x (5+5) enter 25, *, (, 5, +, 5, ), = |

Evaluating functions (value) | To evaluate 2 + log(20) x 5 enter 20, log, *, 5, +, 2, = To evaluate log(30) x 5 – 7 enter 30, log,*, 5, -, 7, = To evaluate In(25) x 2 + 5 enter 25, In, *, 2, +, 5, = To evaluate 5 + In(25) x 2 enter 25, In, *, 2, +, 5,= |

Using sin(Degree), cos(Degree), tan(Degree) | To evaluate sin(45) or cos(45) or tan(45) enter 45, sin or cos or tan To evaluate: tan(45) x 5 + 2 enter 45, tan, *, 5, +, 2, = |

To find 10^{x} |
To evaluate 10^{2.5} enter 2.5, 10^{x} To evaluate 10^{-0.509} enter 10, ^, 0.509, +/-, = To evaluate 10^{-2} enter 10, ^, 2, +/-, = |

Practice is the key to better grasp of the usage of the GATE virtual calculator. Many students and experts advise to practice the simple calculations by hand while using the virtual calculator of GATE 2017 for the more complex ones. It is a fact that using tis will not be that easy as the physical calculator as students are used to the physical one for a period of four years.

**Some Frequently Asked Questions on the GATE 2017 Virtual Calculator:**

**Question**: Can we do calculations involving fractions?

**Answer**: No since this is not a fractional calculator. The NAT questions asked in GATE 2017 need answers only in decimal form.

**Question**: How to convert polar to rectangular form and vice versa?

Ans: Use the appropriate conversions using the calculator as no separate keys have been provided for this.

**Question**: Can we represent Complex numbers?

**Ans**: No. This calculator does not support complex numbers but all questions relating to any area where complex numbers are deemed useful can be solved using this calculator for eg. in power systems or other areas,.

**Question**: Can I use the calculator for Matrix operations like inverse, transpose etc?

Ans: No. All the matrix related calculations have to done manually.

**Question**: Can I solve quadratic, cubic or simultaneous equations?

**Ans**: No since this is a non-programmable calculator. It does not solve equations.

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

**Ans**: No. The calculator can be accessed through web. You need to just load the calculator on your webpage on your computer or mobile. Once it is loaded, you can use it without an internet connection

**Question**: Can I access the values of constants like Planck’s constant, electron mass etc.?

**Ans**: Any constants that are required for solving any questions will be provided in the GATE 2017 question paper. If it is not provided, it is expected that the candidates will know the values of such constants.

**Question**: Can a student use the keyboard for GATE 2017 Question Paper?

**Ans**: No. Students will have to use the mouse only as the key board will be disabled during the entire duration of examination.

**Question**: How should I evaluate 4root16?

**Ans**: The key sequence is 16, yrootx, 4. Remember that the top most box in the calculator will show the sequence of the keys pressed and not the formula.
