Question #23273

1) Given that cosec x + cot x = 3, evaluate the following :
(i) cosec x - cot x
(ii) cos x
2) On the same diagram, sketch the graph of Y = I 3 sin 3/2 x I and
Y = 1 + (6x/5phi) for 0 < x < 2x
Hence, state the number of solution in this interval for the equation
I 3 sin 3/2x I = 1 + (6x/5phi)
