Note that cos x + sin x = 0 cos x = − sin x Now, cos x cannot equal zero, since if it did, sin x = − 1 or sin x = 1, in which case the given equation isn't satisfied. So we can 2cosx+sinx=0

a) D 3cos x. ln(x / y) = ln x - ln y ln xa = a ln x \endalignat.

cos(90-x)=sin(x) Related TI Nspire file. Sine and cosine are cofunctions of each other. The cosine of 90-x should be the same as the sine of x. This implies that graph of sine function is the same as shifting the graph of the cosine function 90 degrees to the right.

For multiplication of two terms be zero at least one of the must be zero. Therefore, at the solution (s), either sin x or cos x has to be zero. Both sin x and cos x can never be zero for same x because squares of those should add up to 1 (one of the principles we used at the beginning of the answer).
