Hello, this is my first post on this forum. I am a high school junior, and I am attempting to build onto my math foundation. Currently, I am finishing Algebra II. Next year, I will not be taking Trigonometry, as my teacher did not recommend me. We were supposed to have straight A's, unfortunately I received a B one quarter. I am seeking resources to self-study Trigonometry and Pre-calculus over the summer. It would be much appreciated, if anyone could provide me with materials , preferably online, to self-study.
