1. Differentiate each of the following. You do NOT need to simplify your answers a. y = sin( 5x3 + 4) b. y = cos? (x4 - 5) C. V = log(x3+4x) d. y = 10tan(xx) 2. Find the equation of the tangent line to the curve y = log (x) , at the point (100, 2).1. Differentiate each of the following. You do NOT need to simplify your answers a. y = 6ev* + In 3 b. y = In(x2 -1) C. y = 8(3x-4)3 2. Find the equation of the tangent line to the curve y = x2 In (x) , at the point (1, 0)
