Convert from Degrees to Radians -40 degrees

Problem

−40

Solution

1. Identify the conversion factor between degrees and radians, which is (π* rad)/180

2. Multiply the given angle in degrees by this conversion factor to cancel out the degree units.

−40⋅π/180

3. Simplify the resulting fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 20

(−40*π)/180=(−2*π)/9

Final Answer

−40=−(2*π)/9
