    Mathematics: Post your doubts here!

    f(x) = 2 – 5(cosx)^2 maximum value of cosx = 1 since it is squared in the equation, cosx = -1 will give the same value for f(x) as cosx = 1 for max value of f(x), 5(cosx)^2 should be 0 therefore max f(x) = 2 for min value of f(x), cosx = 1 or cosx= -1 thus, minimum f(x) = -3

    That's also a correct method, but I prefer this. But I used alpha beta formulaes tan ( alpha - beta ) = ( tan alpha - tan beta ) / ( 1 + tan alpha beta ) And I think it is part of p1 as alpha beta formula is part of p1 syllabus. :) And you are absolutely right :)
