WebApr 4, 2024 · For example, 30 degrees and 60 degrees are complementary angles, as are π/6 radians and π/3 radians. The six trigonometric functions are sine, cosine, tangent, cotangent, secant, and cosecant. Each of these functions has a cofunction that is defined as the function of the complementary angle. WebInverse cosine calculator. Enter the cosine value, select degrees (°) or radians (rad) and press the = button. RapidTables. Search Share. ... arccos(x) = cos-1 (x) For example, If …

Webradian a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 180°/π ~ 57.3 degrees. secant the length of the hypotenuse divided by the length of the adjacent side. Also equals 1/cos(θ) sin WebThe value of csc pi/2 can be calculated by constructing an angle of π/2 radians with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of cosec pi/2 is equal to the reciprocal of the y-coordinate (1). ∴ csc pi/2 = 1. What is the Value of Csc pi/2 in Terms of Sin pi/2?
