Find the product of the complex numbers. Express your answer in trigonometric form.
Z1= 7 (cos15° + i sin 15°)
Z2 = 2(cos110° + i sin110°)

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
