    Find the stationary and inflection points for f(x)=x^3+2x^2-4x+10 ? Determine the nature of each stationary point.
    Just downloading the app so I can upload a photo :P

    Well done!

    Though you still haven't found the points of inflection, and PLEASE don't turn fractions into decimals, that's just disgusting.

    I'm just going to type this one out as I had so much trouble with the app last time XD

    Okay, so the second derivative is 6x+4 so
    6x+4=0
    6x= -4
    x= -4/6
    x= -2/3

    f(-2/3) = 358/27

    Solve for x where 0\leq x < 2\pi

    \text{sin}(x)[\text{tan}^2(x)-1][2\text{sin}(x)+3]+\text{tan}^2(x)=1

    Give answers to 3 s.f. and explain why some of your solutions are invalid.
