Trig Functions- Could anyone tell me why my working is wrong??
the question seems simple..although i don't know what i am doing because it is obviously wrong!. thnkas heaps if anyone can help..
solve
2cosx-(sqrt(3))cosx sinx = 0 for (-pie<=x<=pie)
what i was doing is dividing through by cos x, therefore i obtain:
2-(sqrt(3))sinx= 0
however this statement is flawed! since no value exists for sin x= 2/(sqrt(3))
?it seems simple.. so wat am i doing wrong!1
