The formula to calculate the arctan of a value is:
\[ \arctan(x) = C \]
Where:
The arctan is defined as the inverse value of the tangent of any number or value. It is used to find the angle whose tangent is the given number.
Let's assume the following value:
Step 1: Calculate the arctan:
\[ \arctan(1) = \frac{\pi}{4} \approx 0.785398 \text{ radians} \]
Therefore, the arctan of 1 is approximately 0.785398 radians.
