How to simplify a circle equation
WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have … WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is …

Webe1.1i = cos 1.1 + i sin 1.1. e1.1i = 0.45 + 0.89 i (to 2 decimals) Note: we are using radians, not degrees. The answer is a combination of a Real and an Imaginary Number, which together is called a Complex Number. We can plot such a number on the complex plane (the real numbers go left-right, and the imaginary numbers go up-down):
