the key to the first one is tan(x) = sin(x)/(cos(x)

for the second one, combite the LHS to one fraction and use

sin^2 + cos^2 = 1 - Jun 24th 2007, 01:53 PMjohntuan
ok so i get,

1. (sinx/cosx)/sinx....and im stuck

2. (sin^2x+cos^x)/sinx - sinx/sinx

= sin^2x+cos^2x-sinx/sinx

and im stuck - Jun 24th 2007, 06:12 PMtopsquark
