# Thread: More Cartesian to Parametric Form

1. ## More Cartesian to Parametric Form

Convert from cartesian to parametric equation form?

y = sinx + cosx

2. ## Re: More Cartesian to Parametric Form

This is ridiculous- if the problem is that you do not know what "parametric equations" are, look it up! If you do then make some effort yourself.

3. ## Re: More Cartesian to Parametric Form

Here is my effort.

y = sinx + cosx

x = cost
y = sint

Is this correct?

4. ## Re: More Cartesian to Parametric Form

No, it's not! Do you realize that you are claiming that sin(t)= sin(cos(t))+ cos(cos(t))?

do you really not see that it's just

$\{t,\sin(t)+\cos(t)\}$
