thanks

thanks , that helped me get back on track.

i guess i have done a lot wrong from the start! can you tell me exactly the steps i need to start from the beginning using calculus. all i know is to find y intercept, horizontal asymptote, V.A , using the test values and finding how the graph will look... what else! please help

next i need to find vector and parametric equation and then plot for t ...|

i didnt mean how i will solve it..rather i was concerned about what too do after i get the Y value y =[5+10t]/3

Homework Statement A line has direction angles 60°, 45°, 60° and passes through the point (1, -2, 5). Determine vector, parametric and symmetric equations of this line. Homework Equations The Attempt at a Solution 1/2 i + [root 2]/2 j +1 /2 k parametric equation will be [1 ,-2...

hey , sorry for late response but if i put x=-1+5t in [x+2]/3= [y-1]/2=[z+5]/-3 what will i get after... how do i solve for y

x=-1+5t is part of the question .

actually i was worried about the axis ... in specific the z axis.. i just had this gut feeling like i took -z the wrong direction ...

Homework Statement Write the parametric and vector equations of: x + 2 / 3 = y − 1 / 2 = z + 5/ -3 x=-1+5t and plot a graph of this line when t = −2, −1, 0, 1 and 2. Homework Equations vector: r= [-2,1,-5]+t[3,2,-3] parametric x=3t-2 y=2t+1 z=-3t-5 using...
