1. The 2 men are opposite sides of the building and that the width of the building is negligible.
2. The 2 men's eye level is at the base of the building.
3. The building is perpendicular to the ground.
= 69.3m (3s.f.)
= 208m (3s.f.)
Distance between the 2 men = 69.3m+208m=277m(3s.f.) OR 208m-69.3m=139m (3s.f.)
A. Amplitude is the angle between the real axis of an Argand diagram and a vector representing a complex number.
B. Wavelength is the distance between successive crests of a wave, esp. points in a sound wave or electromagnetic wave.
C. Frequency is the number of waves occurring in 1 second.
D. Phase is the relationship in time between the successive states or cycles of an oscillating or repeating system and either a fixed reference point or the states or cycles of another system with which it may or may not be in synchrony.
E. Characteristics of the waveIt is described using the wavelength, Phase, period, frequency and amplitude of the wave
Transformation 1: y=3sin(x)
Transformation 2: y=sin(2x)
Transformation 4: y=sin(x)+3
Transformation 3: y=sin(90-x)
