Question

Figure $4-1 b$ shows a unit circle in a uv-coordinate system and an angle of $50^{\circ}$ in standard position. Use the definitions of cosine and since to explain why $\cos 50^{\circ}=u$ and $\sin 50^{\circ}=v$ (GRAPH CAN'T COPY)

Answers

In Exercises $39-50,$ verify the identity algebraically. Use a graphing utility to check your result graphically.
$$
\sin x\left(1-2 \cos ^{2} x+\cos ^{4} x\right)=\sin ^{5} x
$$

The Wilson lot size formula, 2DS comes from an optimization problem done in class: It gives the order quantity that minimizes costs given demand D, holding costs H and setup costs S. Assume that D is constant with value D = 50 and S and H are variables, find the linear approximation of Q at S = 32 and H = 8 and use it to approximate ( when $ = 32.80 and H = 7.60.
