Need help in finding derivative to..
Calculus

anonymous · Answer

$$\csc ^2 (\frac{ 3 \pi }{ 4 }$$

anonymous · Answer

the derivative of $$\csc = -\csc(x)\cot(x)$$ 
apply the product rules to find that derivative

anonymous · Answer

you also need the chain rule to solve it

anonymous · Answer

The original question asked to find the derivative of y+ cotx and then to replace x for (3pi/4), which gave me csc^2(3π4). Now i need to find out what the answer is

anonymous · Answer

csc has (3pi/4).. 3π4 is a constant, do you know what you get when you find the derivative of a constant number?

anonymous · Answer

3π/4 derivative is zero.. since the function given needs to use the chain rule.. the whole derivative function is multiplied by the derivative of 3π/4, which is Zero
