Nah not step by step, here's something to think about...

For \dfrac{\sec x - 1}{x \sec x} you can multiply numerator and denominator by \cos x and get \dfrac{1-\cos x}{x}. For limit as x \to 0, this becomes a limit of the form \dfrac{0}{0}, which means you can apply L'Hopital rule.

For the second limit, divide numerator and denominator by x^2. Find the limit of the leftover expression.

For Q2, determine limits as x \to 0 and x \to \pm \infty, what are the the axes intercepts? Does this function have a certain max/min?

For Q3, use a substitution... I'll let you think of what it should be.

and for Q4 we can deal with it if you get there.
