حل {l}{x{(t)}=3+2t}{u=-t^2}{v=u}{w=v}{y=w}{z=y}{a=z}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { x {(t)} = 3 + 2 t }\\ { u = -t ^ {2} }\\ { v = u }\\ { w = v }\\ { y = w }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

برای x،y،z حل کنید

$$x=2+\frac{3}{t}$$

$$y=-t^{2}$$

$$z=-t^{2}$$

$$b=-t^{2}\text{ and }t\neq 0\text{ and }c=-t^{2}\text{ and }u=-t^{2}\text{ and }v=-t^{2}\text{ and }a=-t^{2}\text{ and }w=-t^{2}\text{ and }d=-t^{2}$$
