Question

2. (a) If 4 tan 0 - 3 = 0 then find: (i) cosec 0 (ii) cos 0 + sec o
(b) If cosec 0 = 12 then find: (i) cot e (ii) sec 0 + tan 0.
(c) If sec 0 = 13, then find: (i) tan e (ii) sin 0 + cos 0.​

Answer 1

Step-by-step explanation:

a)tanx=3/4

cosecx=5/3+sec x=4/5+5/4=41/20

b)cosecx=12

cotx=(cosec²x-1)½

cotx=(143)½

secx+tanx=1+sinx/cosx=13/12/((143)½)=13/12(143)½

c)secx=13,

tanx=(sec²x-1)½=(168)½

sinx+cosx=1/13+(168)½/13=1+(168)½/13
