<p>What is a good Precalculus textbook that goes in depth and into more advanced topics? I'm trying to skip directly into Calculus by self-studying over the summer, so I'm not just using it as a supplement for a class. Any other good web resource recommendations like Khan Academy would be appreciated also. Thanks!</p>

<p>This is a free pdf of the stewart pre-calc book I used. It is especially good if you get the stewart’s calculus book afterward. The only thing is that it does not go into really “advanced” topics, but then again that depends on your definition of advanced. It covers everything in typical pre-calc and then intro</p>
<p>As for websites:
PatrickJMT on youtube
Educator.com has trig, pre-calc, and math analysis courses</p>
