Scientific Calculator in Degrees

The Scientific Calculator in Degrees is used to convert real and imaginary numbers to degrees. It uses ellipses to calculate sine, cosine, and tangent functions for a complex number with an argument in radians.

You can enter numbers in this compact scientific calculator either by clicking on the buttons or using the keyboard (to use a numeric keypad Num Lock should be on). This tool has high precision - up to 15 decimals. The angles can be expressed in degrees, radians, or gradians (also known as grads or ranks). For a reference, a full circle is 360 degrees or (2 × π) radian, or 400 gradians.

So in general, this looks like your regular calculator, but it has a couple of features that you might not be used to. For instance, this 'EE'. 'EE' means times 10 to the 'something' power. So what I'm going to do here is write 5.0, 'EE', 3. This is giving me 5.0 times 10 cubed, which is 5,000. So this is scientific notation. A lot of standard calculators don't have this, although most scientific calculators do these days. If you hover over any of the buttons on the CLEP calculator, you'll see this little tool tip that says exactly what that button does. In the case of 'EE', it's your little cheat sheet that says this is the exponent button, value E exponent, and it's used to make your value times 10 raised to the exponent where exponent is an integer. In the case of 5.0'E'3, that's taking your value, 5.0, multiplying it by 10 and raising that to the third power. Either way, it gives you 5,000. (Source: study.com)

Note that the values of trigonometric functions sometimes will be shown in exponential form. For example cos(90deg) amy return 6.123031769111886e-17 instead of zero. This is because the computations are done in radians and are using a rounded value of pi. If this confuses you, try an advanced scientific calculator with an additional "Round" function (which also has a memory register).

In general, the calculator is one of the best tools that you as a mathematician have other than your brain. This is the calculator that the CLEP gives you when you're actually taking their exam. So this is an online calculator. Now this calculator works pretty much like any normal calculator would. There are a few exceptions. First, this calculator has three different modes in addition to the regular calculator mode that you're probably very used to. In addition to that mode, it has a Solver mode, a Data mode and a Graphing mode. It also has a tape history, which you can recognize by this blue circle with an 'H' in it. This history contains all of the previous commands that you've given the calculator, as well as the results of those commands. (Source: study.com)
