Explain how to find the length of a circular arc.
Use the keys on your calculator or graphing utility for converting an angle in degrees, minutes, and seconds \(\left(D^{\circ} M^{\prime} S^{\prime \prime}\right)\) into decimal form, and vice versa. Convert each angle to a decimal in degrees. Round your answer to two decimal places. $$30^{\circ} 15^{\prime} 10^{\prime \prime}$$
Determine whether each statement makes sense or does not make sense, and explain your reasoning. A ride on a circular Ferris wheel is like riding sinusoidal graphs.
Graph \(f, g,\) and \(h\) in the same rectangular coordinate system for \(0 \leq x \leq 2 \pi .\) Obtain the graph of h by adding or subtracting the corresponding \(y\) -coordinates on the graphs of \(f\) and \(g\) $$f(x)=\cos x, g(x)=\sin 2 x, h(x)=(f-g)(x)$$
Determine whether each statement makes sense or does not make sense, and explain your reasoning. I used a tangent function to model the average monthly temperature of New York City, where \(x=1\) represents January, \(x=2\) represents February, and so on.
