Write an article based on this "Consider the point P(2,1){\displaystyle P(2,1)} in the Cartesian plane. Find the distance between the origin O{\displaystyle O} and P{\displaystyle P}. Find the angle between OP{\displaystyle OP} and the positive x-axis. Write down the polar coordinates."
article: Starting at the origin, draw a line segment 2 units along the positive x-axis. Draw a second line segment from that point 1 unit in the positive y direction. You are now at point (2, 1), so label this point P. Draw a line between O and P. This line has length r{\displaystyle r} in polar coordinates. It is also the hypotenuse of a right triangle, so you can find the hypotenuse's length using geometry. For example: The legs of this right triangle have values of 2 and 1. With the Pythagorean theorem, calculate that the hypotenuse's length is 22+12=4+1=52.236{\displaystyle {\sqrt {2^{2}+1^{2}}}={\sqrt {4+1}}={\sqrt {5}}pprox 2.236}. The general formula to find r{\displaystyle r} from Cartesian coordinates is r=x2+y2{\displaystyle r={\sqrt {x^{2}+y^{2}}}}, where x{\displaystyle x} is the Cartesian x-coordinate and y{\displaystyle y} the Cartesian y-coordinate. Use trigonometry to find this value: tan()=oppositeadjacent=12{\displaystyle an( heta )={
rac {opposite}{adjacent}}={
rac {1}{2}}}tan1(12)==26.56{\displaystyle an ^{-1}({
rac {1}{2}})= heta =26.56^{\circ }} The general formula to find {\displaystyle heta } is =tan1(yx){\displaystyle heta = an ^{-1}({
rac {y}{x}})}, where y{\displaystyle y} is the Cartesian y-coordinate and x{\displaystyle x} the Cartesian x-coordinate. You now have the values of r{\displaystyle r} and {\displaystyle heta }. The rectangular coordinates (2, 1) convert to approximate polar coordinates of (2.24, 26.6), or exact coordinates of (5,tan1(12)){\displaystyle ({\sqrt {5}}, an ^{-1}({
rac {1}{2}}))}.

If you aren't logged in, enter your email address (or username) and password before proceeding. This circular icon is in the upper-right side of the page. A drop-down menu will appear. It's in the drop-down menu. Scroll down to the tweet you want to delete, then click it to open it in a pop-up window. If the tweet you want to remove is a retweet rather than a tweet you posted, skip ahead to the "Remove a retweet from your profile" step at the end of this section. It's in the upper-right corner of the tweet's pop-up window. This prompts a drop-down menu. If you want to delete a response that you posted to the tweet, first scroll down to the response. This is in the drop-down menu. Doing so will remove the tweet from your profile. If you retweeted someone else's content, you can remove it from your profile by clicking the green "Retweet" icon below the tweet. You may have to scroll down to see the "Retweet" icon.
