1. I just tried this 6 mark exam question:

solve 4sinx=3tanx between 0 and 360

and got answers of 41.4 and 311.4?

Is this correct because the mark scheme for this question had been missed out. many thanks

3. Did you divide through by sinx? Because that causes you to lose solutions.

if 4sinx = 3tan x then

sinx(4cosx-3) = 0,

so sinx= 0 and cosx=3/4

...

you don't have solutions to sinx=0.
