Question

did you know about polar coordinates??????

Answer 1

Yes?

Answer 2

You mainly want to remember: \[
x=r\cos\theta \\
y =r\sin\theta \\
r^2 = x^2 + y^2
\]

Answer 3

oh really..can you please help me to my project ..it"s okey for you if i ask you what is the meaning of polar coordinates and

Answer 4

Okay sure...

The point of polar coordinates is to locate something. \(r\) tells you how far away it is and \(\theta\) tells you an angle.

Answer 5

This contrasts from Cartesian (x and y) coordinates where x is the horizontal distance and y is the vertical distance.

Answer 6

Sometimes it is much easier to describe things with an angle and magnitude than it is to split them up into horizontal/vertical components.

Answer 7

Do you have any specific questions?

Answer 8

do you know how to graph the polar coordinates/?????

Answer 9

because its too hard for me to graph the polar coordinates

Answer 10

They aren't really easy to graph.

Answer 11

For something like \(r = 5\), you just graph a circle radius 5.

Answer 12

can you please give me an equation to graph a rose or petals???and please graph it...

Answer 13

http://www.wolframalpha.com/input/?i=r+%3D+sin%282theta%29

\(r = \sin(2\theta)\)

Answer 14

yes

Answer 15

how can you define the polar coordinates????

Answer 16

@wio already gave you some good examples and you still don't understand what polar coordinates are?

Answer 17

yes i know,,but it so difficult for me to draw the petals..??can you please draw for me...not a website..only... if okey for you..???
