Question

Value of cos infinity

Answer 1

Thank you for asking that problem of what’s value of cos (infinity). Let me provide you some solution for what the value of cosine infinity.

1- Cosine is an oscillatory function,oscillates between [-1, 1] implying that it values occurring from between minus one and one. 

2- Cos infinity is undefined it will not converge to any definite value.

3- Cos is periodic function. Domain of cos(x) = (-inf, +inf) and Range lies [-1,1] which means if cos(x) as x approaches to infinite thus its value is undefined

4- If cos(1/x) nearby zero there is no number occur in range interval of [-1,1]

5- Look something 7/0 is equal to undefined same case is here

I hope these options will help you.

Answer 2

Cosine is an oscillating mathematical function known to have a value ranging in between -1 and 1.

The exact value cannot be determined since cos value can be detected only for numbers and not for infinity values.

In short, the answer is: -1 to 1
