Dear Friends,
Please, help solve this maths for me:


1. Show that (1 + sin x )(1 + secant x) = Tan x
(1 + cosine x)(1 + cosecant x)

(please, note: it is numerators (1 + sin x)(1 + secant x) over denominators 1 + cosine x) (1 + cosecant x) = Tan x)

2. Express the following angles in degrees
(i) 370 (ii) -430 10' (i.e. 10' is 10 seconds)

3. Express the following angle sin radiant
(i) 21 radiant (ii) п radiant (i.e. pie over 12)
12

Please, give details so I can learn.

Many thanks.

Kindy
