I got 9.5 as well. I substituted 1 into the formula and got 9.5 then substituted 100 into the formula and still got 9.5 so assumed the highest must be 9.5 haha(Original post by DalvirSingh)

Re: Additional maths 30 may 2012Oh Im so confused - whats all this stuff about 9.5? I just assumed the lowest the cosine of anything could be was -1 and did 7-(5*-1) because that gave the highest possible value for the height.(Original post by tomaird)

Re: Additional maths 30 may 2012yeah thats right, people got 9.5 just by putting whole numbers into the equation, but the maximum value could only be achieved with decimal numbers of 't'(Original post by TomMaullin)
