To find the equation of the tangent line to the curve y = sin(2x) at the point x = π/2, we need to find the slope of the tangent line and the coordinates of the given point.
First, we find the derivative of the function y = sin(2x) using the chain rule. The derivative is given by dy/dx = 2cos(2x).
Next, we substitute x = π/2 into the derivative to find the slope of the tangent line at that point. Substituting x = π/2 into the derivative, we get dy/dx = 2cos(2(π/2)) = 2cos(π) = -2.
Now, we have the slope of the tangent line, which is -2.
To find the coordinates of the given point, substitute x = π/2 into the original function y = sin(2x). Substituting x = π/2, we get y = sin(2(π/2)) = sin(π) = 0.
Therefore, the coordinates of the given point are (π/2, 0).
Using the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept, we can substitute the slope (-2) and the coordinates of the given point (π/2, 0) to find the equation of the tangent line.
Substituting the values, we have 0 = -2(π/2) + b. Simplifying, we get 0 = -π + b. Solving for b, we find b = π.
Therefore, the equation of the tangent line to the curve y = sin(2x) at the point x = π/2 is y = -2x + π.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
