### finding stationary points using differentiation

hiya not sure where this should go so sorry if it is in the wrong place

curve is y=(2-x)(x+1)^2

show that one stationary point is at x=-1

find the coordinates if both stationary points

any help much appreciated

### solving the equation 3 sec^2 pheta +7= 11 tan pheta

hi wasnt sure whether the two questions should be together or seperate sorry if they were meant to got together solve the equation 3 sec^2 pheta +7= 11 tan pheta giving all values of x to 3sf in the interval 0<pheta<2pi sorry for the bad setting out dont no how to get pheta and pi signs thanks for a...

### solve the equation 4 cot^2 x + 12cosecx + 1 = 0 for 0<x<360

hi i was wondering if anyone could help me with this question

solve the equation 4 cot^2 x+12cosecx+1=0 giving all values of x to the nearest degree in the interval 0<x<360(should be equal to signs as well but comp doesnt do them)

thanks for any help much appreciated
