i have about 4 problems here all together
my first problem is this question letter H , below is my working out but my answer seems to be wrong so i dont know what im doing wrong.
Find the equation of (i) the tangent and (ii) the normal to the curve.
answer in the back is
i) 17x - y + 27 = 0
ii) x + 17y + 121 = 0
the other 3 problems are
3: x = 1/2
5: x = 1/3/4
in my text book it doesnt really give me examples directly related to this question to solve it so im quite clueless on question 3 , 4 and 5. The other questions in this chapter are primarily based on questions like 4 and 5. So if someone can help me with those questions i'll be able to do the rest.
thx all help is appreciated.
