# (a) Sketch the curve by using the parametric equations to plot points. Indicat with an arrow the direction in which the curve is traced as $t$ increases.(b) Eliminate the parameter to find a Cartesian equation of the curve.$x = \sin t$, $\quad y = 1 - \cos t$, $\quad 0 \leqslant t \leqslant 2\pi$

## (a) See graph(b) $x^{2}+(y-1)^{2}=1$

had a scarce a curve by using the parametric equations to plot points indicated with an arrow. Direction rages the crew. If it's Tristan this hey, but he's a zero. X equals zero. Why is the country Cyril? But he's got high over, too. I asked you what you want. Why could want. But he is too high. Accede with zero. Why is he going to two? Tea is to go to three Pi over too. Axe connected. One. Why would two Why, when he is he going to too high X is equal to zero. Why is he here, too? Zero. Then let's catch the curve. Cyril, Cyril. One one zero to negative one one zero zero. That's a curve is like this. It's a row is a direction. In Vegeta Cliff, it's trist. Aston Chris's Party B. Eliminate its A. Permitted to find a Scottish equation of the crew party. We have Axe Squire US one minus y square. It's the cultural sign. It's square us, who signed He square, which is equal to one so X squared. Plus why minus one square is a good one. This is a Scottish in question
