How to find the equation of the tangent (parallel) given an x value?
- Find the derivative of the equation (dy/dx)
- Find the y value by plugging x to the original equation
- Find the gradient by substituting x values with the respective x coordinate
- Use slope-intercept or point-slope formula to find equation

Method to solve small increments
- Find the derivative of the equation
- Use the concept that dy/dx = change(y)/change(x)
- Substitute the amount of change in x
- Substitute x into the derivative
