The simple way with any calculator is to multiply your result by (pi/180) because degrees/360=radians/(2*pi)

Use the power button that looks like " ^ ". The first number will be the number you want cubed and the second one will be the exponent you want (in this case, 3)
Example: If you want to cube 4, input it like this: 4 ^ 3. Hit enter and you will get 64.

To enter a power of ten, use EE, the shifted function of the key just above the 7 key. For example, to enter 2 times ten to the 60th, press 2 2nd [EE] 6 0

To raise a number to another, use the ^ key, just to the left. For example, to calculate two raised to the 60th, press 2 ^ 6 0 =

Make sure your calculator is in degree mode.
It is probably in radian mode so it can't calculate the inverse sin.
To change this, go to Mode -> Deg.
Hope this helps, cheers!

To calculate the square root of 9, press
2nd [square-root] 9 ) =

The square-root is the shifted function of the x-squared key, just to the left of the 7 key. The close-parenthesis is needed to balance the open-parenthesis automatically inserted by the square-root function.

For x to the 2nd power, that is the same as x squared.
There is a button on the left side that shows an x with a small 2 above it and to the right.
Punch x into the calculator then push the x squared button and read the answer.
For example, press 4 then the x squared button and the display should read 16.

There is also a button right above the 7 that reads x with a small -1 above it and to the right.
I'm not sure whether the E(sigma) pertains to that, however.
Press 4 then the x to the -1 power and the display should read 0.25

I hope this helps, let me know.

First put the calculator in degree mode.
To convert from fraction to a decimal number first enter your fraction or, mixed number. I'll convert a mixed number to a fraction first since, I don't have a key for the symbol that shows that a number is a fraction on my keyboard. Example: [3][A b/c][1][A b/c][2][A b/cd/e][ENTER]
3/2 should be entered at the home screen. While at the Home screen enter, [2nd][FD][ENTER]
1.5 should now be displayed at the Home screen.
As you can see it is really just using the [A b/c] key to enter in your fraction and, [FD] key to do the converting. The [A_b/cd/e] key isn't necessary because, mixed numbers will convert to decimal numbers just like fractions do. I just don't have the key to show a fraction symbol that the calculator uses. So to show that symbol, I used the / symbol with the fraction number.
