Help me diffrenciate question 2 (1/y)Help me find the tanget and the normal for the 2nd questions.And help me find the answers for the last 2 questions as well with an explanation These both are under one question in my book but different partsThank you ^^

Note: for any given equation, if we differentiate a variable y we must add- Question 1. Differentinto (2) = xy3 + cot(3xy) Question 2: find the equations of tangent and normal lines for each given function: 1) y2 + x2 =5 (x1, y1) = (2,1) 2) g(x) *+ 2 x -3 => discontinuous at x = x - 2 25 25 Show that the function f(x) = 2 - V3 - x2 is a continuous on the interval [-1,1]
