# NumPy: Calculate inverse sine, cosine, and tangent for all elements in a given array

## NumPy Mathematics: Exercise-22 with Solution

Write a NumPy program to calculate inverse sine, inverse cosine, and inverse tangent for all elements in a given array.

Sample Solution:-

Python Code:

``````import numpy as np
x = np.array([-1., 0, 1.])
print("Inverse sine:", np.arcsin(x))
print("Inverse cosine:", np.arccos(x))
print("Inverse tangent:", np.arctan(x))
```
```

Sample Output:

```Inverse sine: [-1.57079633  0.          1.57079633]
Inverse cosine: [3.14159265 1.57079633 0.        ]
Inverse tangent: [-0.78539816  0.          0.78539816]
```

## Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

```str="+++Welcome python+++"
str.strip()

print(str)```

Output:

`+++Welcome python+++`
