Question

My tinspire calcualtor showing wrong answer, answer should be 0

Answer 1

No, my friend, the calculator is not showing the wrong answer, it is just showing it in the wrong format.

You see, you are correct. It should be 0 radians.

However, the calculator is giving the answer in degrees.

`sin(11*\pi )` in degrees is in fact 0.567..., while it is also 0 radians

Here, let me show you these screenshots to help you understand what I mean. I hope this helps
