Claudia Fragapane. Claudia Fragapane (born 24 October 1997 in Bristol) is a British artistic gymnast. She came to prominence at the 2014 Commonwealth Games, where she was the first English woman to win four gold medals since 1930.
The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. tangent right triangle trigonometry the unit circle.
That means a positive value will yield a 1st quadrant angle and a negative value will yield a 2nd quadrant angle. The domain of the inverse tangent function is (ââ,â) and the range is (âÏ2,Ï2) . The inverse of the tangent function will yield values in the 1st and 4th quadrants. The same process is used to find the inverse functions for the remaining trigonometric functions--cotangent, secant and cosecant.
