Question

HOW CAN I GRAPH THIS?
X=7SINt+SIN7t
Y=7COSt+COS7t

Answer 1

@mathmale @mathwizkevin18 ?

Answer 2

Here's a plot of the function:

http://www.wolframalpha.com/input/?i=parametric+plot+x%3D7Sin%5Bt%5D%2BSin%5B7t%5D%2C+y%3D7Cos%5Bt%5D%2BCos%5B7t%5D

There's no way to express it in rectangular form (i.e. y as a function of x or vice versa), so eliminating the parameter isn't possible.

To plot it by hand, you could plug in values of \(t\).

Answer 3

alright good tip! i had no idea how to approach it...

Answer 4

so what values.... can i use the one in the graph you plotted for me?
