How do you convert YX to polar form?
The polar form is rsin(θ)=rcos(θ) . The points of the line y = x are given by r = 0 and sin(θ)=cos(θ) or, instead, θ=π4andθ=−3π4 .

How do you convert polar coordinates to rectangular coordinates?
The easiest way to remember the formulas for converting polar to rectangular coordinates and vice versa is to draw the right triangle at the origin with sides x and y, hypotenuse r, and angle θ. From there, it’s easy to see that: x 2 + y 2 = r 2 x = r cos
What is the formula for converting Cartesian to polar?
Cartesian to Polar Conversion Formulas r2 = x2 + y2 r = √x2 + y2 θ = tan − 1(y x) Let’s work a quick example. Example 1 Convert each of the following points into the given coordinate system.
How do you convert equations from one coordinate system to another?
We can also use the above formulas to convert equations from one coordinate system to the other. Example 2 Convert each of the following into an equation in the given coordinate system. Convert 2x −5×3 = 1+xy 2 x − 5 x 3 = 1 + x y into polar coordinates. θ into Cartesian coordinates.
What is the actual angle of this point in polar coordinates?
Therefore, the actual angle is, So, in polar coordinates the point is ( √ 2, 5 π 4) ( 2, 5 π 4). Note as well that we could have used the first θ θ that we got by using a negative r r. In this case the point could also be written in polar coordinates as ( − √ 2, π 4) ( − 2, π 4).
