Sort by:

the answer is -10 as the minimum value of the expression Asinx + Bcosx +C = 0 is C - (A^2 + B^2)^1/2

A very very easy question. The answer is $$-\sqrt{6^2 + {(-8)}^2} = -\sqrt{100} = -10$$. @Nitesh Chaudhary lets just forget our disputes and be friends. Youe choice now.

Thanks for mentioning me man. I think that you've got your answer, but still

$$min(asin(x)+bcos(x)+c=0)= c- \sqrt {a^2+b^2}$$
