Coordinate Geometry Plane Geometry Solid Geometry Conic Sections TrigonometryQuestion: Find a cartesian equation for the polar curve: a) r=3cscθ y = 3 b) r=−2tanθsecθ y = Find a cartesian equation for the polar curve: a) r=3cscθ y = 3. b) r=−2tanθsecθ y = There are 3 steps to solve this one. Step 1.I think you should go on the way you started with: r=sqrt(X^2+Y^2); and theta=atan(Y/X)); but you must pay attention to the points where X is negative.Cylindrical coordinates have the form (r, θ, z), where r is the distance in the xy plane, θ is the angle formed with respect to the x-axis, and z is the vertical component in the z-axis.Similar to polar coordinates, we can relate cylindrical coordinates to Cartesian coordinates by using a right triangle and trigonometry.y = 30000. z = 45000. To convert these coordinates into spherical coordinates, it is necessary to include the given values in the formulas above. However, we will do it much easier if we use our calculator as follows: Select the Cartesian to Spherical mode. Enter x, y, z values in the provided fields.How do you convert #r=6cosθ# into a cartesian equation?

Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. Cartesian to Polar | DesmosThe way I attempted the problem was by converting the polar equation to a parametric (cartesian) equation and using the formula dy dt dx dt = dy dx - and setting that equal to two. This did not seem to get me the right answer. Set the equation for the slope equal to 2 and solve for θ . dy dx = f(θ)cos(θ) + f ′ (θ)sin(θ) − f(θ)sin(θ ...Added May 14, 2013 by CDewhurst in Mathematics. converts Cartesian coordinates to Polar.
