One, two and four are limitations of psychological experiments.
it is upside down
but I know that there is somebody that has been answering those question.
The first thing you have to realize is that
tangent is the
slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:
Next use
product rule (I recommend watching videos if you're confused):
Next substitute you x-value (π/2) into your derivative:
So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)
So we get our equation:
So our answer is E
