Please help me with this mathematics question. Thanks.?

(a) Find the equation of the tangent at the point (1,2) on the curve y = x³ + 3x - 2 (b) Use your GCD to find the coordinates of the point where this tangent meets the curve again. SOLUTION From the given equation. Y = x³ + 3x - 2 Differentiate to find the slope.

Dy/dx = 3x² + 3 When x = 1 (From the given point) dy/dx = 3(1)² + 3 dy/dx = 3(1) + 3 dy/dx = 3 + 3 dy/dx = 6.

Y = x³ + 3x - 2 tangent at the point (1, 2) y' = 3x² + 3 at x = 1, the slope of the tangent line = 6 (y - 2) = 6(x - 1) or y = 6x - 4 the line intersects the curve at: 6x - 4 = x³ + 3x - 2 x³ - 3x + 2 = 0 (x - 1)² (x + 2) = 0 x = - 2...so, y = - 16 (- 2, - 16) is the other point of intersection.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
