12/26/2016 · cos ? = x/r. r = 5 / (1 + cos ?) ==> r (1 + cos ?) = 5 ==> ? (x^2 + y^2) [1 + x / ? (x^2 + y^2)] = 5. ? (x^2 + y^2) = 5 – x ==> x^2 + y^2 = 25 – 10x + x^2 ==> y^2 + 10x = 25. I hope my answer helped you. Have a nice day! kattyahto8 and 126 more users found this answer helpful. heart outlined. star. star.
3/18/2019 · Cos angle formula There are many formulas in trigonometry but there are few most important basic formulas in trigonometry when it comes to a right-angle triangle. The Cos theta or cos ? is the ratio of the adjacent side to the hypotenuse, where ? is one of the acute angles.
Rewrite in rectangular form: r=6 cos theta I got (x-3)^2+y^2=6 . Pre calculus. Find the rectangular equation for the given polar coordinates: R=(7/(5+4sin theta )) Algebra2. solve the equation cos theta – tan theta * cos theta = 0 for 0. theta ; 2 pi My answer is pi/4,5pi/4, change the polar equation r=5/1 + cos ( theta ) to rectangular form. How do I do this? Thank you! 🙂 Math. Rewrite in rectangular form: r=6 cos theta I got (x-3)^2+y^2=6 . Calculus. Write the polar equation in rectangular form. r = 12 sin theta Write the rectangular equation .
Cos Theta Formula | Cos Angle Formula and Questions, Cos Theta Formula | Cos Angle Formula and Questions, Trigonometric Identities – math, Trigonometric Identities – math, 1/3/2016 · Most typically, the conversion equations would be written with a theta rather than at t as: r^{2}=x^{2}+y^{2}, x=rcos(theta), y=rsin(theta). After the substitution mentioned above, the equation x^{2}+y^[2}=5x can be rewritten as x^{2}-5x+y^{2}=0, or x^2-5x+(-5/2)^2+y^{2}=(-5/2)^2, or (x-5/2)^{2}+y^{2}=(5/2)^{2}
