A circle of radius 7 is centered at the point (-8, 9). Find a formula for f(q) (Use the variable q for the angle.)

Question

amistre64 · Answer

x^2 + y^2 = r^2

cos^2 + sin^2 = 7^2

49cos(q) + 49sin(q) = 49  ???  hows that

amistre64 · Answer

ack!!... forgot to include the off centerd  lol

amistre64 · Answer

i was sooooo close...

amistre64 · Answer

(x+8)^2 +(y-9)^2 = 49

x^2 +16x +64 +y^2 -18y +81 = 49

amistre64 · Answer

cos^2(q) + 16cos(q) + sin^2(q) -18sin(q) +96 = 0  maybe??

anonymous · Answer

just to parametrize maybe they are looking for 

x= -8+7cos(q)

y= 9+7sin(q)

i don't know if that is what is meant maybe?

amistre64 · Answer

hard to tell with the question; I was gonna parametric it, but thought maybe not :)
