Have you used a calculator before? We are pretty sure you would have. Every single person in the world would have used a calculator for their day-to-day purpose. There are various types of calculators available in the market. Some are simple calculators doing basic calculations, while some are scientific or financial calculators doing complex calculations. Hence, before diving into the modes and their functions of a calculator, let’s briefly recapitulate these calculators.

Types Of Calculators
Modern electronic calculators are used to carry out many tasks such from basic maths tasks to arithmetic to complex mathematics. Calculators have enhanced our ability to perform basic calculations and also helped us to understand and fulfil these calculations at a bigger scale and speed.
The basic calculators are used to do general-purpose calculations in home and office. Scientific calculators are designed to solve problems in mathematics, science, and engineering.
The first scientific calculator was manufactured in 1968, and then thousands of portable scientific calculators have been invented. One such calculator was TI 30, designed by Texas Instruments.
TI-30 was launched in 1976. After that, TI 30 went under many transformations in its design under the brand name of TI. The latest model launched by TI is TI-30X Pro.
As we know now that there are many mathematical calculations made using scientific calculators, and one of them is calculating angles.
How To Measure An Angle In A Calculator?
There are many ways to measure an angle. Just as feet and meters are different systems to measure length, degree and radian are the two approaches to measure an angle. The most common way is to measure degrees used in most US high school students and colleges. In degrees, a full circle is 360 degrees, and a right angle is 90 degrees. The other way to measure angle is radian, wherein a full-circle is 2-pi radians, and a right angle is pi/2 radians.
Now when you are working with trigonometric functions, you often have to change the system of your angle that is measured. By default, the angle mode in the calculator is in degree mode, but if you want to calculate the angle in radian, then the calculator has to be put in the radian mode.
Let us understand how to put the calculator to radian mode.
Putting The Calculator To Radian Mode In TI 30
If you want to calculate the measure of angles in radian instead of degrees or gradian, then using the MODE button, you can change the mode of the device. The new models of TI 30 generally come with the MODE button, but in older models of TI-30, instead of the MODE button, DRG(Degree, Radian, Gradian) button is used.
