### What happens

I’m trying to do the problem #74 of codeabbey, but results with many decimals are a little bit different

### What do you understand or find about that problem

For this problem, codeabbey results require to be calculated with an accuracy of `1e-7`

or better. Trigonometric functions are defined as infinite series which results are more precise as long is the series. I think the precision developed for Lobster is not enough to achieve the codeabbey results

### You make any workaround? What did you do?

I calculated the same in WolframAlpha manually and I got exactly the same results that are in codeabbey, so that’s why I think it’s a problem with the Lobster functions precision. I can’t develop my own trigonometric functions because if series are shorter the result could be different, and if are longer the result could be different too.

### Evidences

Codeabbey problem:

This is what I got

and what should be

And the operations I’m doing are

```
6*sin((30*9.5)°)+10
6*cos((30*9.5)°)+10
```

and you can check their results in

### I need help with

I need to know what I should do, because I need the same values to submit successfully the problem, or if I should find another exercise because of the limitations of the functions.
