Find the exact value of the trigonometric function at the given real number. sin(4π/3), sec(7π/3), cot(-2π/3)

Solution:

There are six basic trigonometric functions used in Trigonometry. These functions are trigonometric ratios.

The six basic trigonometric functions are:

sine function, cosine function, secant function,

co-secant function, tangent function, and co-tangent function. 

sin(4π/3) = -0.866

sec(7π/3) = 2

cot(-2π/3) = -0.577

Therefore, the exact values of the trigonometric function at the given real number are -0.866,2, -0.577 respectively.

Find the exact value of the trigonometric function at the given real number. sin(4π/3), sec(7π/3), cot(-2π/3)

Summary:

The exact value of the trigonometric function at the given real number. sin(4π/3), sec(7π/3), cot(-2π/3) are -0.866,2, -0.577 respectively.
