Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out. WebOct 14, 2024 · By definition of the inverse tangent, tan − 1 y is some angle between − 90 ∘ and 90 ∘, but it's not the only one that satisfies tan x = y. To get other solutions, you have to add or subtract a multiple of 180 ∘. A calculator will tell you that x = tan − 1 1 = 45 ∘, but it's also true that tan ( 225 ∘) = tan ( 45 ∘ + 180 ∘ ...

Calculating Inverse Tangent - Mathematics Stack Exchange

WebThe sign of a trigonometric function is dependent on the signs of the coordinates of the points on the terminal side of the angle. By knowing in which quadrant the terminal side of an angle lies, you also know the signs of all the trigonometric functions. WebFor tan 20 degrees, the angle 20° lies between 0° and 90° (First Quadrant ). Since tangent function is positive in the first quadrant, thus tan 20° value = 0.3639702. . . ⇒ tan 20° = tan 200° = tan 380°, and so on. Note: Since, tangent is an odd function, the value of tan (-20°) = … justin bieber where are u now
