This is what I did. Slide the bar from OFF to ITEM. Hit the blue button on the left TIME/DATE, then hit the equals (=) sign to set the date and time. Slide the bar from ITEM to OFF. When I want to print the date on my till tape, I hit TIME/DATE. (Once, prints the date and a second hit prints prints the time.) Hit CE/C to get $0.00 to display and ready to calculate.

It depends on the calculator - some have the sqrt function, with others you need to use the exponent.
Any calculator that serves with a calculation function only can be used in the gate exam. A scientific calculator is recommended, but you should use whatever you are comfortable with and have practiced with.
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
5tanx=1 turns into tanx=1/5 then you use a calculator use the calculator function tan^(-1) this function should be the 2nd function of tan then in the parenthesis that come up type in 1/5 you should get .1974 therefore tanx=1/5 => x=.1974

It depends on the type of HP calculator you are using. You may only use a four-function, scientific, and graph calculator that does not come with other functions.
Most complex calculators have pi built into it. But you can use 3.14 if you only have a four function calc.
