How can I do this step by step? Please help me with this assignment guys. Thank you.

Step -by -step:

1. Convert the csc and cot functions to their sine and cosine equivalents
2. Simplify the result
3. Look for an opportunity to apply other well-known identies. such as sin^2x+cos^2x=1 and its alternative versions, such as 1-sin^2x = cos^2x.
4. Simplify.
