Find parametric equations for the tangent line to the curve with the given parametric equations at the specified point. x = t, y

DochEvi [55]

Answer:

Step-by-step explanation:

At the point (0, 1,0) t = 0

Find the tangent vector:

$\frac{dx}{dt}= 1$

$\frac{dy}{dt}= -4e^{-4t}$

$\frac{dz}{dt}=5-5t^4$

The tangent vector for all points $\vec v(t)$ is

$\vec v(t) = \hat {i}-4e^{-4t}\hat{j}+(5-5t^4)\hat{k}$

$\rightarrow \vec v (0)= \hat{i}-4\hat{j}$

The vector equation of the tangent line is

$(x,y,z) = (0,1,0)+s(\hat{i}-4\hat{j})$

The parametric equation for this line are

$x= s$

$y=1-4s$

$z=0$
