Use implicit differentiation to find the: write the solution of each number

9. y' of sec²x+csc²y = 9


ans. y'= tanx sec²x / coty csc²y


10. g(y)= cos y / 3 - 3 siny

Try to use grouping symbols when it is not clear what is intended. The problem: is it (1/3)cos(y) or is it cos(y/3)? Or it could even be: cos(y)/[3 - 3sin(y)]

Yes, that was clear, but for #10 it is not so clear. My guess is that [3 - 3siny] is the denominator of the fraction with cos(y) as the numerator--but it is a guess.
