Hi need solutions so i can understand. I will rate helpful!!

I. Find the derivatives of the following functions : 1 . If y = ( x 2 + * + 1 ) 2 , find y". Ans. 2 . If x 2 + 42 = a2 , find y". Ans. I. Solve for y' : 1. y = 4x Tan ( 1+ 4x ) ] Ans. 2 . y = In ( 5 - e4 * ) Ans. 3. " te = 4 Ans . 4. Cos ( x y ) = x - y Ans. 5 . 9 = 109 8 (5 - X2) Ans. II. Find the equations of tangent and normal : y = 2 @ ( 1 , 2 ) Ans. T : N : 2. y =X3-2@ ( 2 , 8 ) Ans. T
