This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form \(a^2 = b^2 + c^2 - 2bc \cos{A}\) to calculate the length. \(\text{BC}^2 ...
Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...
