Reciprocal Trig Functions
1 Cot x = 1/ tan x
2 Sec x = 1/cos x
3 Cosec x =1/sinx
4 Counter example questions:
4.1 Let x = 30 Plug into equations Is it the same true/ false
5 Tan^2 x + 1 =sec^2 x
6 1+ cot^2 x= cosec^2 x
7 Equations using Reciprocal trig functions:
7.1 Use correct trig function to get a quadractic equation with the same function
7.1.1 Rearrange and solve the quadratic finding two answers
7.1.1.1 Rearrange to find x
7.1.1.1.1 Use cast diagram to find the other corresponding answers
