• How can I rewrite 8 cos 4x in terms of cos x? If you could give a detailed explanation, that would be great!
  
• How do I find the inclination of θ (in radians and degrees) of the line with slope m? (Round your answer to 3 decimal places.) m = -3.
  
• How do I find the inclination θ (in radians AND degrees) of the lines passing through the points? (-√3, -1), (0, -2)
  
• How do I find the inclination θ (in radians and degrees) of the line? 6x - 6y + 7 = 0.
  
• How do I find the center, vertices, foci, and eccentricity of the ellipse? #x^2 + 8y^2 − 8x − 16y − 40 = 0#
  
• How do I find the center, vertices, foci, and eccentricity of the ellipse? #6x^2 + 2y^2 + 18x - 18y + 30 = 0#. I'm really struggling with completing the square.
  
• How do I find x and y values of the parametric equations? (When t = 1, 2, 3, and 4) x = √t y = 5 - t After doing that, how do I find the rectangular equation by eliminating the parameter?
