 Answer 50 /5 10 jimthompson5910 x^2y^2 = 16 can be written as (x0)^2 (y0)^2 = 4^2 We see that the second equation is in the form (xh)^2 (yk)^2 = r^2 where (h,k) = (0,0) is the center r = 4 is the radius The polar form of the equation is simply r = 4 Why is this?. The area element d A in polar coordinates is determined by the area of a slice of an annulus and is given by d A = r d r d θ To convert the double integral ∬ D f ( x, y) d A to an iterated integral in polar coordinates, we substitute r cos ⁡ ( θ) for , x, r sin.

Replace x x and y y with the actual values r = 2√2 r = 2 2 θ = tan−1 ( 2 −2) θ = t a n 1 ( 2 2) The inverse tangent of −1 1 is θ = 135° θ = 135 ° r = 2√2 r = 2 2 θ = 135° θ = 135 ° This is the result of the conversion to polar coordinates in (r,θ) ( r, θ) form (2√2,135°) ( 2 2, 135 °).  As noted above we can get the correct angle by adding p p onto this Therefore, the actual angle is, θ = π 4 π = 5 π 4 θ = π 4 π = 5 π 4 So, in polar coordinates the point is ( √ 2, 5 π 4) ( 2, 5 π 4) Note as well that we could have used.

Https//googl/JQ8NysConverting the Rectangular Equation 3x y 2 = 0 Into Polar Form.  b) Option C y = x Stepbystep explanation a) First, we know that a circle centered at the origin of radius R is written as x^2 y^2 = R^2 Then x^2y^2=25 can be rewritten as x^2 y^2 = 5^2 This is a circle of radius 5 Then in polar form, this can be written as r = 5 b) Now we have the angle 225° For rectangular coordinates (x, y).  Explanation By definition, you pass from (x,y) coordinates to (ρ,θ) coordinates by ρ = √x2 y2 θ = arctan( y x) ( with some changes depending on the sign of x and y ) So, in your case, the equation becomes simply ρ2 = 16 This means that the equation represents all the points with distance 4 from the origin, which is a circumference with radius 4, centered in the origin.

 r=8sintheta If (r,theta) is in polar form and (x,y) in Cartesian form the relation between them is as follows x=rcostheta, y=rsintheta, r^2=x^2y^2 and tantheta=y/x Hence, x^2(y4)^2=16 can be written as x^2y^28y16=16 or x^2y^28y=0 or r^28rsintheta=0 or r(r8sintheta)=0 dividing by r r8sintheta=0 or r=8sintheta.   The above notes are true, but you know that (x4)^2 y^2=16 is a circle of radius 4 with center at (4,0) You also know that the circle r = 2a cosθ is a circle of radius a with center at (a,0) in xy coordinates So, this one will be r = 8cosθ 👍.  Convert the Cartesian equation x^2 y^2 = 16 to a polar equation r² = 16/cos2è r = 4 r² = 8 help please im stuck between 2 answers Calculus Write the polar equation in rectangular form r = 12 sin theta Write the rectangular equation (x 7)^2 y^2 = 49 in polar form Trig.

A complex number is a number of the form a bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1For example, 2 3i is a complex number This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 1 = 0 is imposed Based on this definition, complex numbers can be added and.  4 Polar Form of a Complex Number by M Bourne We can think of complex numbers as vectors, as in our earlier example See more on Vectors in 2Dimensions We have met a similar concept to "polar form" before, in Polar Coordinates, part.
