Math 1309-001: Review for Exam #4

f(x) = cos (ln x) f(x) = ln[cos (2x2 + 3)] 4. Find the first derivative: f(x) = cos (ex + 5) f(x) = 2x3∙ esin (4x+1) f(x) = sin−1(e3x) 5. Use implicit differentiation to find the first derivative: 3x – xy + 1 = 0. x3 + y4 + xy + x + y = 1. 6. Find the equation of the line tangent to the graph of f(x) at the indicated point. y = 4 cos … ................
