Question

if sec = 5/4find the value of sin -2 cos /tan -cot​

Answer 1

Step-by-step explanation:

hope it helps you out with the situation

Answer 2

Step-by-step explanation:

Sec = 5/4

sec = Hyp/Base

Hyp = 5

base = 4

Perpendicular = 3 ( by Pythagoras theorem)

Sin = 3/5

cos = 4/5

tan = sin/cos = 3/4

cot = 4/3

3/5 - 8/5 / 3/4 - 4/3 = -12/7
