my teacher never explains anything to my class and expects us to know it by heart. i understand some of it but not all of it. so if you can show me how you work these problems and the answer i would find it very helpful!
using the complementary angle theorem:
1. cos10 degrees/ sin80 degrees
2. 1+tan squared five degrees- cosine squared 85 degrees
3. cot 40 degrees- sin 50 degrees/sin 40 degrees
4. 1- cos squared 20 degrees- cos squared 70 degrees
