question 8

Essay

Use the parallelogram rule to find the magnitude of the resultant force for the two forces shown in the figure. Round to
one decimal place.
-The equation $\sin 2 x - \cos 3 x = - 4$ has no solution in the interval $[ 0,2 \pi )$ . Explain what this tells you about the graph of $y = \sin 2 x - \cos 3 x + 4$ .
