## How do you write functions acs(arc cos) and asn(arc sin)

## How do you write functions acs(arc cos) and asn(arc sin)

(OP)

Could anyone please tell me how to write qbasic functions acs(arc cos) and asn(arc sin), and to input arguments for the functions via the keyboard. Th results should be in

radians.

radians.

Arctan:

^y **********

-------------------*------------------>x

Arccos:

(-1, 2pi)

* ^y

* |

***

(0, pi)| **

| *

| *(1, 0)

---------+----*------>x

Arcsin:

(-1, pi)

^y *

| *

| *

(0,0)| **

--------***--------->x

(1,-pi) |

The latter two graphs show the ENTIRE function. The range of the functions is as implied by the endpoints. As for the graph of arctan, it has the same range as arcsin, but its domain is the reals.
