Formula Used in “Tangent of a Circle Calculator”
The standard formula for calculating the length of the tangent (T) from a point (P) outside a circle to the point of tangency (T) on the circle is given by:
T = √(d² – r²)
In this formula:
- T = Length of the tangent from point P to the circle
- d = Distance from the external point P to the center of the circle
- r = Radius of the circle
Step-by-Step Breakdown of the Formula
- Identify the Distance (d): Measure or determine the distance from the external point P to the center of the circle. This measurement is crucial as it directly influences the length of the tangent.
- Identify the Radius (r): Find the radius of the circle. This is the distance from the center of the circle to any point on its circumference.
- Square the Distance (d): Calculate the square of the distance (d²). This will help in finding the difference when subtracting the radius squared.
- Square the Radius (r): Calculate the square of the radius (r²).
- Calculate the Difference: Subtract the square of the radius from the square of the distance (d² – r²). Ensure this value is non-negative as the square root of a negative number is not defined in real numbers.
- Take the Square Root: Finally, take the square root of the result obtained to find the length of the tangent (T).
Example Calculation
To illustrate how to use the formula, consider this real-world example:
| Input | Description |
|---|---|
| d | 8 units (Distance from point P to the center of the circle) |
| r | 4 units (Radius of the circle) |
Using the inputs, we can apply the formula:
Step 1: Calculate d²:
8² = 64
Step 2: Calculate r²:
4² = 16
Step 3: Find the difference:
64 – 16 = 48
Step 4: Take the square root:
T = √48 ≈ 6.93 units
Thus, the length of the tangent from point P to the circle is approximately 6.93 units.
