*In this Introduction, I will give a general overview of the topic of Trigonometry, tips on how to learn and study well, and then go into more detail.*

1)You have to first identify the right triangle in this scenario. What function will give you the side you need to solve for? First, you determine the right function to use (tan, sin, and cos) based off of which sides are given (Hyp, Adj, Opp). What trigonometric function involves both the opposite and the hypotenuse? I recommend buying a math book as a source to find a variety of problems, and learn concepts.

4) Apply the function to that angle, solve for the side, and calculate. If you identify your difficulties, be sure to ask for help!

For example, divide an isosceles triangle into two congruent right triangles.

Step 4: Mark the angles or sides you have to calculate.

Example 2: Suppose that from atop a 100m vertical cliff a ship is spotted at an angle of depression of 12 degrees. Also, find the distance from the top of the cliff to the ship.
