I am unsure of how to take the derivative of this equation. It may be the exponents that are giving me trouble but I'm not sure exactly. Find the equation of the tangent line to the curve 4e^xy = 2x + y at point (0,4). On the left side, is the "xy" the exponent ...

**Calculus**

Find the equation of the tangent to the graph of f(x)=2x^4 (to the power of 4) that has slope 1. Derivative is 8 x^3. This equals 1 at x = 1/2. At this point the y-coordinate is f(1/2) = 1/8. The equation of the tangent line is thus: 1/8 + 1*(x-1/2) = x - 3/8 Thank you for ...
