    I think I may have messed up the question where you had to use the substitution to find the area underneath the curve, I ended up a negative value? I just cancelled the negative sign cos it's an area and was hoping to go back to it but I ran out of time

    Yeah personally I thought 27 sounded like a good number hahaha
    I don't think it would take 27 years for a population to rise by 25%, unless the animals are big on condoms or something

    Last part of the differential Q (7) I used radians to solve for t. I'm confused which one, degrees or radians, was appropriate? I thought when solving for trig it was radians by default.

    I think you needed to give it indegrees, 'cause in radians it didn't even make a year. I'm not sure though. I believe they will take both correct
    I used radians because I thought that calculus with trig functions only worked with radians. I'm not sure if that's the right thing to do though.

    It said coordinates at which dy/dx is 0! So there should be more than 1

    I used tangent.
    d=tan31.82 * distance of AB
    I used the sine rule, anyone else?
