please help me work out and answer every question on the page I don't understand any of it.

b) tan20 - tan 0 sin2 0 = sin' 0 15. If tan 0 = 6, then determine sec 0. seco = 1+ 6 1 - /sinzo Han = 6 Cos 20 = 1 - Sin ? (9 JSec. 37 Sec = 6.1 cos:0 16. If cos 0 = , then find sin . 13. Solve the following equations for 0 5 0
