Question

We know that,
Sin0° = 0
cos0° = 1
tan0° = 0

If we divide sin0° by tan0°, then we get cos0° = 1

but 0/0 does not equal to 1. WHY? ​

Answer 1

since you know that any number multiplied with 0 will give result 0 and if you try to multiply this zero by zero form by any number then it will give infinite results therefore called this form as indeterminate because its value cannot be defined as you can see if you multiply any number then it will give any result according to the number ( value of cos 0 is actually evaluated by using the concepts of limit )
