Webx = 3cos(theta) y = 2sin(theta) and I need you to know that the object was rotating in the positive direction. Then I will make the substitution: time = t= theta and give you the equations x = 3cos(t), y = 2sin(t) instead. Even though the equations are identical, you know what direction the object rotated, because t is always increasing. ;) WebQuestion: Which of the following pairs express the same graph? \[ \begin{array}{l} f(x)=3 \sin \left(\theta-\frac{\pi}{2}\right), g(x)=3 \cos (\theta) \\ f(x)=3 \sin ... did goodwill hunting win an oscar
