Question

find the period of cos(4x + 9 / 5)​

Answer 1

Answer:

the answer would be 2π as the power of cos theta is odd n=1

Answer 2

Answer:

here is your answer

Step-by-step explanation:

If a function f(x) is periodic with T , then the function f(ax+b) is periodic with

∣a∣Tcos(x) is periodic with 2π

So, cos( 54x+9 )=cos( 54x + 59 ) is periodic with

2π

=

4/5 ×2π

= 25π
