Answer: cot(θ)
Cot Calculator is used to calculate the trigonometric cotangent of a given angle. You can specify the angle in degrees or radians. The Cot Calculator computes the cotangent of given angle and provides a step by step solution.
How to calculate cot(θ) using graph?
Step 1 - Draw unit circle
Draw a unit circle with \(O(0, 0)\) as the center of the circle on the graph paper.
Step 2 - Draw line with angle θ
Draw a line from center of the circle making an angle θ with X-axis.
Mark the point as \(P\), where the line touches the circle.
Step 3 - Form Right Angle Triangle PQO
Draw a perpendicular line from \(P\) to the X-axis.
Mark the point as \(Q\), where the perpendicular line touches the X-axis.
Now, we have a triangle, PQO with right angle at \(Q\), \(∠POQ = θ\), and \(OP = 1\) unit.
Step 4 - Calculate cot(θ)
In a right angled triangle, Cotangent of an angle (θ) is the ratio of the length of the adjacent side to the length of the opposite side.
The formula for cot(θ) is:
cot(θ) == (Length of Adjacent side)/(Length of Opposite side)
From triangle PQO,
cot(θ) == OQ/PQ
Measure the lengths \(PQ\) and \(OQ\) on the graph and find the ratio \(OQ/PQ\), that ratio is the value of cot(θ).
