Find the Derivative - d/dx y=-csc(x)-sin(x)

Problem

d()/d(x)*(−csc(x)−sin(x))

Solution

1. Identify the function to be differentiated, which is y=−csc(x)−sin(x)

2. Apply the sum rule for derivatives, which allows for the differentiation of each term individually: d(y)/d(x)=(d(−)*csc(x))/d(x)+(d(−)*sin(x))/d(x)

3. Apply the derivative rule for the cosecant function, where d(csc(x))/d(x)=−csc(x)*cot(x)

4. Apply the derivative rule for the sine function, where d(sin(x))/d(x)=cos(x)

5. Combine the results, accounting for the negative signs in the original expression.

6. Simplify the signs: −(−csc(x)*cot(x))=csc(x)*cot(x)

Final Answer

d()/d(x)*(−csc(x)−sin(x))=csc(x)*cot(x)−cos(x)
