There is a lot of sin and cos functions involved in calculas, and you have to be able to deal with them.  
Practice really does make perfect, so just practice lots!  Libraries have other text books and teaching materials you can use to self teach.  It doesn't have to be a big thing, maybe just an hour on two nights a week.  
Also, it will help if you have a good calculator, like a graphics calculator, but they can be expensive (mine was about $170)
Good luck!
