1)(1cos^2x)(csc x) ?
Is this equal to sec x?
2) Expand: log7 3 sqrt x / x^2y
3) Find and simplify: f(g)
F(x) = x^2 + 2x g(x) = 2x
x^2 + 2x(2x) = x^2 + 4x
Is this correct?

cos(tan + cot) = csc only simplify one side to equal csc so far I got this far: [((cos)(sin))/(cos)] + [((cos)(cos))/(sin)] = csc I don't know what to do next
