    i need help please.. its urgent .. someone please help me

    ok cool. thanks for the answer. but then I want to derive it and find the critical point.
    tanθ=5.6X/(X^2-d^2-5.6d)
    sec^2 θ dθ/dX=5.6((-d^2-5.6d-X^2)/(X^2-d^2-5.6d)^2 )
    -d^2-5.6d-X^2=0
    X^2=-d^2-5.6d
    X=√(-d^2-5.6d)
    I don't think this is right.. please help me..
