In Euler's formula, this 
In Euler's formula, this function is multiplied by i. This function's namesake wave is integral to Fourier analysis and represents constant, periodic oscillations. On the unit circle, this function is positive in the first and second quadrants. Additionally, this function is used to represent the y-value of a unit circle arc. For 10 points, identify this trigonometric function that is the inverse of cosecant and, for a right triangle, gives the ratio of the opposite side over the hypotenuse.
