Variables x and y are such that y = e 2x + e -2x . a. Find

Question:

Variables x and y are such that y = e^2x + e^-2x.

a. Find dy/dx.

b. By using the substitution u = e^2x, find the value of y when dy/dx = 3.

c. Given that x is decreasing at the rate of 0.5 units s^-1, find the corresponding rate of change of y when x = 1.
