# NumPy: Compute sine, cosine and tangent array of angles given in degrees

## NumPy Mathematics: Exercise-21 with Solution

Write a NumPy program to compute the trigonometric sine, cosine and tangent array of angles given in degrees.

Sample Solution:

Python Code:

``````import numpy as np
print("sine: array of angles given in degrees")
print(np.sin(np.array((0., 30., 45., 60., 90.)) * np.pi / 180.))
print("cosine: array of angles given in degrees")
print(np.cos(np.array((0., 30., 45., 60., 90.)) * np.pi / 180.))
print("tangent: array of angles given in degrees")
print(np.tan(np.array((0., 30., 45., 60., 90.)) * np.pi / 180.))
```
```

Sample Output:

```sine: array of angles given in degrees
[ 0.          0.5         0.70710678  0.8660254   1.        ]
cosine: array of angles given in degrees
[  1.00000000e+00   8.66025404e-01   7.07106781e-01   5.00000000e-01
6.12323400e-17]
tangent: array of angles given in degrees
[  0.00000000e+00   5.77350269e-01   1.00000000e+00   1.73205081e+00
1.63312394e+16]
```

## 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+++`
