http://www.mathwords.com/c/cofunction_identities.htm WebFor sin 48 degrees, the angle 48° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 48° value = 0.7431448. . . Since the sine function is a periodic function, we can represent sin 48° as, sin 48 degrees = sin (48° + n × 360°), n ∈ Z. ⇒ sin 48° = sin 408° = sin 768°, and so on.

WebSin 15 Degrees Using Unit Circle. To find the value of sin 15 degrees using the unit circle: Rotate ‘r’ anticlockwise to form a 15° angle with the positive x-axis. The sin of 15 degrees equals the y-coordinate (0.2588) of the point of intersection (0.9659, 0.2588) of unit circle and r. Hence the value of sin 15° = y = 0.2588 (approx) WebOct 27, 2024 · Converting tangents to degrees requires you to apply the arctan function to the tan of the angle you’re interested in. The following expression shows how to convert tangents to degrees: \text {Angle in degrees} = \arctan (\tan (θ)) Angle in degrees = arctan(tan(θ)) Simply put, the arctan function reverses the effect of the tan function. WebThe value of a trig function of an angle equals the value of the cofunction of the complement of the angle. Cofunction Identities, radians. Cofunction Identities, degrees. sin (90° – x) = cos x. cos (90° – x) = sin x. tan (90° – x) = cot x. cot (90° – x) = tan x. huntington bank types of accounts
