What is the principal value of a trigonometric function?

Principal value of trigonometric functions - Examples. Example 1 : Find the principal value of the following. cos x = √3/2. Solution : cos x = √3/2 > 0. Principal value of x must be in [0, π]. Since cos x is positive the principal value is in the first quadrant.

What are the different types of trigonometry values?

Trigonometry values are based on three major trigonometric ratios, Sine, Cosine, and Tangent. Similarly, we can write the trigonometric values for Reciprocal properties, Sec, Cosec and Cot ratios. Sec θ . Cos θ =1

What is the principal value of angle?

The solution in which the absolute value of the angle is the least is called principal solution. For example the value of cos o° is 1, the value of cos 2π, 4π ,...... are also 1. But the 0 is known as principal value.

What are principal values in logarithms?

Motivation. Each value of k determines what is known as a branch (or sheet ), a single-valued component of the multiple-valued log function. The branch corresponding to k =0 is known as the principal branch, and along this branch, the values the function takes are known as the principal values .

26 hours ago The solution in which the absolute value of the angle is the least is called principal solution. In other words, the solutions of a trigonometric equation for which 'x' lies in the interval 0 to 2π, i.e., 0 ≤ x ≤ 2π, are called the principal solution. The process of finding the solution set is called solving the trigonometric equation.
