Tangent Function:
From: | To: |
The tangent function is a fundamental trigonometric ratio that relates the opposite side to the adjacent side of a right-angled triangle. It's one of the three primary trigonometric functions along with sine and cosine.
The calculator uses the tangent formula:
Where:
Explanation: The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side.
Details: The tangent function is widely used in mathematics, physics, engineering, and navigation. It helps in solving problems involving right triangles, calculating slopes, and determining angles of elevation or depression.
Tips: Enter the lengths of the opposite and adjacent sides in any consistent units. Both values must be positive numbers.
Q1: What is the range of tangent values?
A: Tangent values range from negative infinity to positive infinity, as the function is periodic with period π.
Q2: What happens when the adjacent side is zero?
A: The tangent becomes undefined (approaches infinity) as the angle approaches 90 degrees.
Q3: Can tangent values be negative?
A: Yes, in quadrants II and IV where either opposite or adjacent (but not both) are negative.
Q4: How is tangent related to other trig functions?
A: tan(θ) = sin(θ)/cos(θ). It's also the reciprocal of the cotangent function.
Q5: What are practical applications of tangent?
A: Used in calculating heights of buildings, angles in construction, navigation, and in many physics formulas involving angles.
