If x and y are connected parametrically by the equations given in Exercises 1 to 10, without eliminating the parameter,find $$\frac{\mathrm{d} y}{\mathrm{d} x}$$

Question 1.
x = 2at2, y = at4 Question 2.
x = a cos θ, y = b cos θ Question 3.
x = sin t , y = cos 2t  Question 4.
$$x=4 t, y=\frac{4}{t}$$  Question 5.
x = cosθ – cos 2θ y = sinθ – sin 2θ  Question 6.
x = a (θ – sin θ),y = (1 + cos θ) Question 7.
$$x=\frac{\sin ^{3} t}{\sqrt{\cos 2 t}}, y=\frac{\cos ^{3} t}{\sqrt{\cos 2 t}}$$  Question 8.
$$x=a\left(\cos t+\log \tan \frac{t}{2}\right), y=a \sin t$$  Question 9.
x = a sec θ, y = b tan θ  $$\text { If } x=\sqrt{a^{\sin ^{-1} t}}, y=\sqrt{a^{\cos ^{-1} t}}, \text { show that } \frac{d y}{d x}=-\frac{y}{x}$$
