Question

(2) If 5 sin 0 - 12 cos 0 = 0 then find the value of sec 0.
(3) Show that, sin? 0 (1 + cot? 0) = 1​

Answer 1

Answer:

(2) 5sin 0=12cos 0

5sin 0= 12/sec 0

sec0=12/5 sin 0

Answer 2

Answer:

5 sin -12 cos 0=o

5sin0=12cos0

sin/cos=12/5

tan0=12/5

1+tan2 0=sec0

1+12/5=sec0

1+144/25=sec0

25+144/25=sec0

169/25=sec0

13/5=sec0

sec0=13/5
