The equation used to convert degrees to radians is rad = (deg x pi)/180, where rad stands for radians, deg is degrees and pi is equal to 3.142. Radians and degrees are ways to measure an angle in a circle.
Know MoreA simple example using this equation is to convert 60 degrees into radians. By substituting 60 degrees into the equation, one finds that radians = (60 x pi)/180 = pi/3 = 3.142/3 = 1.047 radians.
Students can manipulate the equation rad = (deg x pi)/180 such that they multiply both sides of the equation by 180 degree and divide by pi to get the new equation (rad x 180)/pi = deg. This is the equation to convert from radians to degrees. As a check that this equation is correct, students can use the result of 1.047 radians in this equation, which should give the answer 60 degrees.
A circle has 360 degrees, and 2 pi radians equals 360 degrees. From this relationship, it is easy to see that pi radians is then equal to 180 degrees.
To find the approximate radian measurement of angles like 2 pi or pi/2, one has to multiply by the value of pi given as 3.142 to get 6.283 and 1.571 respectively.

Word equations are commonly used in chemistry and are used to show common chemical reactions. Word equations are written with the name of the substance instead of the chemical abbreviation.
Full Answer >A demand equation is an algebraic representation of product price and quantity. Because demand can be represented graphically as a straight line with price on the y-axis and quantity on the x-axis, a demand equation can be as basic as a linear equation. They can also be much more complex, however, and can require significant algebraic manipulation.
Full Answer >An inverse equation, or inverse function, is an equation that reverses another equation. If an equation will give the value of y when providing x, the inverse equation will give the value of x when providing y.
