Bobbym, to get from step 2 to 3 you use the result  sin(pi/2 - x) = cos(x).

Here are the list of Calculus books I feel are good:

Calculus, 7th Edition - James Stewart.
Calculus and Analytic Geometry - Thomas & Finney.
Thomas' Calculus - Thomas, Weir, Hass.
Calculus: A Complete Course - R. A. Adams.
Advanced Calculus Demystified: David Bachman.

Personally, I think Calculus and Analytic Geometry by Thomas & Finney is the best Calculus book you will ever come across.

All the best smile
