Answer:
How though?
Step-by-step explanation:
A b c d... and x are all representing 1 unknown #. The particular letter
is not revelent unless its like f (x) =.... which just means y but g(x) sometimes means graph.
otherwise it doesn't matter at all
Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]
C Becuase it’s the same triangle but doubled
