Solve conditional trigonometric equation (between 0 and 360)

sin^2(Theta)-cos^2(Theta)-cos(Theta)=-1

Polar function

Graph an ellipse as a polar function with center at the pole and parameterized by the lengths of the semi-major and semi-minor axes. Can someone please show me step-by-step on how to do this?

Polar function

Graph an ellipse as a polar function with a focus at the pole and parameterized by the eccentricity e and the distance d between the focus and a vertical directrix. ----------------------------------------------------- Please show me how step-by-step on how you would graph this. Thanks

Help in getting problem setup correctly

I have tried setting up this problem using right triangles but have not been able to solve it correctly. This problem is not as simple as it looks. It cannot be assumed that the bottom of the circle is tangent to a line drawn across the bottom. Solving for that one triangle is part of the solution. Theta is given as 20 degrees and the book supplies the answer as .69341. The answer is not 0.625. Thank you

Help with setting up the construction of problem

I would like help in setting up the construction to solve for the value of X in this problem. I have tried to form right triangles to solve it but not been able. The value of Theta is 52 degrees and the value of X the book gives is 1.1763.
