Double Cot Find Sin(a) Cos(a) Tan(a) Csc(a) Sec(a) And Cot(a) ... Involving Double Angles?

Find sin(a) cos(a) tan(a) csc(a) sec(a) and cot(a) ... involving double angles? - double cot

Can someone me a detailed step by step in this direction. I just need this answer to get the ball rolling

find sin (a) cos (tan) (a), CSC (a) s (a) and children (one ..)

cos (2a) = 3 / 5 and 0deg \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, u0026lt 2 (a) \\ \\ \\ \\ \\ \\ \\ \\; 90deg
