Solve trigonometric equations and real-world problems involving applications of trigonometric equations using technology when appropriate.


Remarks


Example: The diagram above shows a vertical cross-section through some strata, showing that the width (W) of the middle layer, as measured on the upper surface, is not the true width of the layer, T, which is assumed to be constant. Calculate the true width, T, when theta=30º, W=100 meters.

Example: Solve 2 sin(x) +1=0 on the interval [0, 2¶)
