# How To Solve Trig Problems Find to the is a support wire used to hold a newly planted tree in place, preventing it from bending or up-rooting during high winds. • It is assumed that the tree is vertical, making it perpendicular with the ground.• This problem deals with "opposite" and "hypotenuse" making it a sine problem.

In this lesson, we'll be looking for the angle(s) that make an equation true.

The table and diagram below are designed to help you understand and remember the key ratios that make up basic trig functions.

Okay, let's try one where the domain is pre-defined for us. Remember, you can treat cot(x), cos(x), and other trig functions like algebraic variables.

Since cot(x) is the reciprocal of tan(x), it will be 0 every time tan(x) is undefined (0/1 instead of 1/0).

• From the top of a fire tower, a forest ranger sees his partner on the ground at an angle of depression of 40º.

If the tower is 45 feet in height, how far is the partner from the base of the tower, to the • Remember that the "angle of depression" is from a horizontal line of sight downward.Trigonometric equations, equations that involve trigonometric functions (ratios of the sides of a right triangle), can be solved using algebraic steps, trig rules, and conversions.A domain limitation establishes upper and lower limits for possible input angles, otherwise you have to allow for an infinite number of solutions in positive and negative rotations. We have over 200 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.A trigonometric equation is an equation that involves trigonometric functions, ratios of the sides of a right triangle.Trig functions help us solve many kinds of problems.Within the given domain (-180° to 180°), the 90° angle and -90° angle meet that condition, so that's two of our answers. Well, remember that the cosine is the ratio of the adjacent side to the hypotenuse in a triangle, so sine and cosine can never be larger than one or smaller than -1.In this case, the cosine solutions have no associated angles.Since a circle with a radius of 1 will have a circumference of 2π, any angle can be expressed as part of that 2π rotation. A table of values has been included below to help you with your trig adventures: Glancing at our table, we can see that our two values for x will show up at 90° (x = 1), 210° (x = -1/2), and 330° (x = -1/2).Remember, there are also an infinite number of other positions (in other rotations) where x also appears.The following is a simple example: 30° is just one of the solutions.An angle is a measure of rotation, and if you keep rotating you'll get more angles with the same sine.
