Let me know if that works for you.

Otherwise, I'd be more than happy to help you out.

I don't mind solving the question, but I think that if you read this page once, you'll always be able to solve these and it will make your life a lot easier 

Haha yeah I had that too, but if you try again it'll send you through.

You have a great day too 

Yeah now that you say it; 

you wrote

That's all right,

I wouldn't have known how else you could've referred me to that page.

Nope, but it wasn't that hard to go to page 801.

for 32, the center of the circle is at (p,q) = (0,0) and the radius 3

Since the general equation of a circle is given by

$$(x-p)^2+(y-q)^2 = r^2$$ where (p,q) is the center and r the radius

the equation of this circle is

$$(x-0)^2 + (y-0)^2 = 3^2 \Rightarrow x^2+ y^2 = 9$$

Similarly for 36 we find

(p,q) = (-1,1) and r = 2

Therefore

$$(x--1)^2 + (y-1)^2 = 2^2 \Rightarrow (x+1)^2 + (y-1)^2 = 4$$

Yes, but we can define the equation which defines all solutions to this problem.

If we add both equations we have

sf+sp = 14+21

s(f+p) = 35

This is part of the surface the equation desribes.

the inverse sin, also noted as asin, arcsin or sin^-1 is the opposite of a sin

For example if we have

sin(b) = c then b = asin(c)

So if you want to type it in your calculator you can enter asin(0.8)

However sin(0.8)^-1 means something completely different than sin^-1(0.8) , but I dont think you mean the first one right?

anyway, asin(0.8) = 53.13 degrees.
