Fill the blanks with y,$\qquad$x,$\qquad$and$\displaystyle \qquad \frac{y}{x}$
See p. 409, Definition of the Trigonometric Functions Let $P(x, y)$ be the terminal point on the unit circle determined by the real number $t$. Then for nonzero values of the denominator the trigonometric functions are defined as follows. $\sin t=y \qquad \cos t=x\qquad \displaystyle \tan t=\frac{y}{x}$ $\displaystyle \csc t=\frac{1}{y}\qquad \displaystyle \sec t=\frac{1}{x}\qquad \displaystyle \cot t=\frac{x}{y}$ ------------------ Fill the blanks with y,$\qquad$x,$\qquad$and$\displaystyle \qquad \frac{y}{x}$
