    Find the local extrema then classify them

    So this is a very long answer for a question worth 4 marks. Would it be a good idea to keep the explanation, or to have it strictly math only?

    Solving for the speed of volume

    Is this correct?

    Determine what happens to the rate of change of the population over time

    So you'll have lim t---> infinite , the function in the denominator will grow faster, so as t grows, P'(x) approaches zero. I believe another way to see this is to note that for t---> inf, P(x)---> 24, therefore reaching a constant value, with zero rate of change. My rate would be zero, right?

    Determine the equation of the tangent line to the function given

    sorry, I realized I made an error in my math upon determining the equation. It would be ##y=2x-\frac{3\pi }{2}##.

    Determine the equation of the tangent line to the function given

    sorry for the late follow-up, I checked my work again, and my slope is 2. My b value, upon calculation, is ##-3\pi ##. Would my final equation be ##y=2x-3\pi##?

    Differentiate, but do not simplify: ##y=3ln(4-x+5x^2)##

    please excuse me horrible writing, it's supposed to be a 4

    Differentiate and simplify: f(x)=sin^2(2x)-cos^2(2x)

    yes, sorry, I forgot to include the question! here it is:

    Determine the point on the given curve

    So I'd leave my final answer as (0.693,2.772)?

    At what point(s) on the given curve is the tangent line horizontal?

    It's always relieving and reassuring when I get a heads up from brilliant tutors online :) Thank you!
