Find the maximum(minus) answer of this equation:

(sinx-2)(cosx+ $\displaystyle \frac{\sqrt{3}}{2}$ )=0

Is it -$\displaystyle 30^0$?

Thanks.

sinx-2 is never zero.

so you left with:

cosx=-sqrt(3)/2)

can you find the solutions for that? - May 29th 2011, 11:45 AMArchie Meade

Are you attempting a solution using differentiation or by other means ?
