x = 3 (1 - cos t) y = 3 (t - sin t) mencari dy/dx nya berapa sich..??. tolong klo ad yg bisa di bantu ea...mksih..

x = 3 - 3cos t
dx/dt = 3sin t
dt/dx = 1/3sin t

y = 3t - 3sin t
dy/dt = 3 - 3cos t

dy/dx = (dy/dt)(dt/dx)

[tex] \frac{dy}{dx} = \frac{3 - 3cos t}{3 sin t} [/tex]

[tex] \frac{dy}{dx} = \frac{1 - cos t}{sin t} [/tex]
