Exam 5: Trigonometric Functions of Real Numbers

When an airplane flies faster than the speed of sound, the sound waves that are formed take on a cone shape, and where the cone hits the ground, a sonic boom is heard. If is the angle of the vertex of the cone, then sin where V is the speed of the plane and M is the mach number, then what is the mach number if the plane is flying at 891 m/sec.? mach number is __________ .

.Sketch the graph of the function , .
