    You are given that theta (which I'll show as () )is an acute angle....
    Sin() = root5
    3

    Find the exact value of tan ()

    I spent ages trying to use inequalities, and then ended up leaving it out and not understanding the mark scheme.

    Zacken can help with that.

    By the way, did you mean \sin\theta=\sqrt{5} up there, or did you mean to include the 3 in the equaton?

    Thanks for the tag. BTW, \sin \theta = \sqrt{5} isn't possible since \sin is bounded between in [-1,1].

    As for the original poster, draw a right angled triangle. Label one of the angles \theta. Label the opposite side \sqrt{5}, label the hypotenuse 3; so \sin \theta = \frac{\text{opp}}{\text{hyp}} and then find the adjacent using pythagoras and hence \tan \theta = \frac{\text{opp}}{\text{adj}}.

    I get it now, I never remember to draw a triangle. And soon as you mentioned it, I understood. Thanks!

    Did everyone here take their maths gcse in year 10 then?

    Well, I didn't - I'm doing both GCSE maths and the FSMQ this year, but I think I'm mostly focusing on additional maths anyway. How about you?

    Woah, that's really good. Congrats on that grade!

    I'm guessing you'll be taking both Maths and FM next year?

    Nah, that's fine - you were basically stating facts. :dontknow:

    And you shouldn't hide an achievement like that.

    If you're planning on doing four full A-levels, that's still a lot. :lol:

    I'm doing my GCSE and fsmq this year. I'm pretty much doing 95% additional and 5% gcse, since the gcse should be simple.

    Okay, wow that's harsh. Our school's saying that four A levels are the maximum.

    I'm doing this exam, unfortunately it clashes with another exam (General Studies, which is also an extra subject I'm doing). I have no plans to revise for either GCSE maths or fsmq, except learning the kinematics equations - anyone have some good ways to remember them? I can only remember v=u+at :/
