(B) The functions j and k are given by j(x)=2log10(x+3)-log0 x-log03 (tan x) (cot x) k(x) = CSC X (i) Rewrite j(x) as a single logarithm base 10 without negative exponents in any part of the expression. Your result should be of the form log 10 (expression). (ii) Rewrite k(x) as a fraction involving secx and no other trigonometric functions.
