Question

If A ≥ B, then cos A ≥ cos B. Is it true ? Justify your answer​

Answer 1

Answer:

it is not true

Step-by-step explanation:

cosines of numbers reduce as numbers increase

cos0=1

cos90=0

90 is greater than 0

but cos0 is greater than cos90

Answer 2

Answer:

if A=90

B=0,then A>B

cos A > cos B

90 > 0

0 > 1

so it is not true
