SOLUTION: Would really appreciate help with the following question on my task sheet. Find dy=dx as a function of x and y when: (a) y - x sin y - 3x^2 - 1 = 0 and (ii) x^2y^3

SOLUTION: Would really appreciate help with the following question on my task sheet. Find dy=dx as a function of x and y when: (a) y - x sin y - 3x^2 - 1 = 0 and (ii) x^2y^3 - x

Question 375002: Would really appreciate help with the following question on my task sheet.

Find dy=dx as a function of x and y when:
(a) y - x sin y - 3x^2 - 1 = 0
and
(ii) x^2y^3 - x^2 + 3y - 3 = 0
Finally
(c) (1 - x^2) tan^-1 y = 3
Need to brush up on these, have looked in engineering mathmatics book, having difficulty, and the instructor isnt really approachable
Thanks
