Question

which is greater cos6° (or)cos 15° with detail explanation ​

Answer 1

Answer:

cos6 is greater than cos 15

Step-by-step explanation:

we know between 0 to 90-degree cos is a decreasing function i.e.

it decreases as the angle increases.

example-

cos0=1>cos30=√3/2>cos45=1/√2.cos60=1/2>cos90=0

So,cos6>cos15
