**Convert Degrees to Radians (Â° to rad) - Inch Calculator**

Note: Itâ€™s far easier to change your calculator to give the answer in degrees instead of radians (in this case, it would be 30 degrees), and then convert it manually by multiplying by pi and dividing by 180 (as others have said). Youâ€™d have (30 pi)/180, which reduces to pi/6.... In general, the inverse function of tan is known as arctan, and might sometimes also be denoted as sin^-1 (x) (Here -1 does not refer to the power of sin x but to the notion of an inverse function).

**Degrees to Radians Conversion**

6/07/2011Â Â· tinytim thanks for your answer, though it's confusing I got that exact same fraction using an online calculator but that answer seems weird for an exam question. And no, typing 3.14159 won't make it 22/7, because it's not exactly that.... Certain models of the Texas Instruments TI30X scientific calculator can convert from degrees to radians. The user can change the function of the calculator through the buttons on the face.

**How can i change my scientific calculator from radians to**

To convert radians to degrees, you multiply by $\frac {180}{\pi}$. The standard positions for angles and headings are different, as The Chaz has commented. To go from a regular angle of $\theta$ to a heading, the heading is $\frac {\pi}2 - \theta$ in radians or $90^\circ -\theta$ in degrees.... Note: Itâ€™s far easier to change your calculator to give the answer in degrees instead of radians (in this case, it would be 30 degrees), and then convert it manually by multiplying by pi and dividing by 180 (as others have said).

**Convert radian/second to RPM Conversion**

In this section we see examples of how to use radians instead of degrees when finding the values of sin, cos, tan, csc, sec and cot of angles. The angle 4.5 degrees. Notice the difference between these last two. Without the degree sign, 4.5 means "4.5 radians". It is important to set your calculator... 24/11/2008Â Â· look at the top of your scientific calc. normally it will have a list of secondary functions for each button. In my calculator, I press *shift* and 4 to put it in degree mode. I have a casio fraction calculator.
