A SIMPLE ONLINE SCIENTIFIC CALCULATOR

WITH TRIGONOMETRIC, INVERSE TRIGONOMETRIC, HYPERBOLIC, AND INVERSE HYPERBOLIC FUNCTIONS

<---------------------------------------------------------------------------------------------------------------------------------->

This tool has 16 math functions including trigonometric, inverse trigonometric, hyperbolic, and inverse hyperbolic functions. It features three angle modes: degrees, radians, and grads, and includes two constants: pi and e.

No special computer skills are required to use it, and the interface is straightforward and intuitive. You can use this gadget online just as you would a real pocket calculator.

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.

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).

For those not familiar with the hyperbolic functions, they are analogs of the circular trigonometric functions. The hyperbolic functions are defined by removing imaginary units appearing in the Euler's complex exponentials.
