I hope this is the right forum for this question.
Find the equation(s) of the tangent(s):
(i) from the point (1,0)
(ii) with gradient
ok for (i) for this equation, i tried differentiating the equation and plugging the values of x and y but i get -2/0 which definitely cannot be the case.
the answer is supposed to be .
All I need would be some pointers, like where i should be looking. Thanks
