Dec 3, 2021 ... x^2+y^2 +2x - 4y - 8 = 0 Here are 2 methods: 1️⃣ Compare quadratic x²+y²+2fx+2gy+c = 0 & centre (-f,-g) 2f = 2 ⟹ f =1 also 2g = -4 ⟹ g = -2 so ... For each of the exponential functions, convert it to the form y = Aekx. (a) y = 5x Solution: y = e(ln 5)x. (b) y = 52x Solution: y = e(2 ln 5)x. Bestimmen Sie das Volumen des RotationskSrpers, der durch Rotation des durch den Funktionsgraphen von y = x/x 2-16 (x e [ 4; 8 ]) und der. Substitute (y−2)2−4 ( y - 2 ) 2 - 4 for y2−4y y 2 - 4 y in the equation x2+y2−2x−4y=4 x 2 + y 2 - 2 x - 4 y = 4 . ... (x, y) = x2 + y2 − 2x − 4y is ~i +j. Solution: The direction of fastest change is in the direction of ∇f =< 2x−2, 2y−4 > . Therefore we want ∇f =< 2x−2, 2y −4 > ... 4 9 XY X 4 Y 9 49315 9 49 2 Z4 2 Z[ \4 4 1 9 ]1 Z19 Z4 5 4 54 9 5 31 4 31 2 Z ^1 5 2219 5 Y 5 31 19 Y Z42 45Y 9 994 1 9 Z45 Z4 Z ^1 [ Z454 4 1^24Y 54 49 2 9919 ...
