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 x at . y = 3 tan4x at . y = (1 + x) cos … ................
