# Eliminate the parameter

1) x=3-2t     y=2+3t     2) x=sqrt(t)      y=1-t       3) x=4+2cos(theta)     y=1+2sin(theta)     4)...

# Eliminate the parameter????

Eliminate the parameter   x=4+2 cos∅   y=1+2 sin∅ I think i can solve it like this but i am not sure x=4+2cos∅ x-2=4cos∅ x-2/4=cos∅

# How do I convert from parametric equations to rectangular form?

Write the rectangular form for the parametric equation x=cosθ ; y=4sinθ

# how do you find intersections with the functions?

I understand parametric equations for the most part, but i always have trouble with finding their intersection points. I would be glad for a second opinion. Thanks so much!

# How do I eliminate the parameter to write a parametric equation as a regular equation?

What are the steps?

# Parametric equations

A baseball is pitched horizontally at 95 mph, or about 140 feet per second. How long does it take for the ball to reach the batter at home plate, which is about 60 feet from the mound? Parametric...

# Find two different sets of parametric equations for the following equation: y= (1/(x^3)) I need the answers to this.

I have the answers {x=2t, y=(1/8t^3) } and {x=t, y=(1/t^3)} If I have the wrong answers could you explain how to get the right ones? I have to answer this in class tomorrow and I'm insanely paranoid...
