# How To Solve Trigonometry Word Problems (Don’t let the fancy names scare you; they really aren’t that bad).With Right Triangle Trigonometry, we use the trig functions on angles, and get a number back that we can use to get a side measurement, as an example.

However at high tide the water level rises to \$70\$ meters. Amplitude refers to half the difference between the highest and lowest point on the curve.

Find the trigonometric function that represents the depth of the water over time if it's peak high tide at \$ AM\$. \$B\$ is the horizontal stretch or shrink that can be found from the period of the function.

Adjacent - The side that is next to the angle of reference that is not the hypotenuse. Third Slide: Tricks on how to find the value of the sin, cos, tan of a specific angle. Sin 30° = 1 (opposite)/2 (Hypotenuse) so it equals ½ = .5(calculator). You can use the pythagorean theorem to check that these are valid right triangles.

Right Triangle - A triangle with one ninety degree angle. There are other examples of finding the ratio defining the trigonometric functions of specific angles.

So we can use the formula for area of a triangle which is: The average time between a high tide and a low tide at a port is \$6\$ hours.

The average depth of water at the port is \$ meters.I will also provide tips on how to study and learn this topic well.This tutorial requires you to already know some basic algebra and geometry.Today it is used in engineering, architecture, medicine, physics, among other disciplines.The 6 basic trigonometric functions that you’ll be working with are sine (rhymes with “sign”), cosine, tangent, cosecant, secant, and cotangent.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!(only for the top triangle)d) use a calculator to find the numerical value of x. Answers: Left Triangle- A) Hyp=5m, Adj=4m, Opp=3m B) Sin C = ⅗, Cos C = ⅘ Tan C = ¾ Right Triangle- A) Hyp=x, Adj=unknown side, Opp=2,500. This step was made to help you understand what the strange numbers and decimals on your calculator mean whenever you find the sin, cos, or tan of an angle. The first step would be to figure out what is given. Then just type that into your calculator to find the result. We have learned what is a right triangle, opp, adj, hyp, sin, cos, tan, how to solve for an unknown side using trigonometry, the pythagorean theorem, values of trigonometric functions for specific angles, applying trigonometry to real world problems, and using the inverse sine to find the value of an angle given the sides.(top Triangle)Tip: Use Pythagoras Theorem To solve for the third unknown side. B) Sin 23 = 2500/x, Cos 23 = unknown side/x, Tan 23 = 2500/unknown side. Fourth Slide: These are world problems that are found in real-life situations so that you can put your knowledge into more practical use! 3)Find the angle you need to use for your situation. The goal is to find the measure of an angle given at least two sides. The opposite (7) and the hypotenuse (25) are known. The arcsine is just another word for the inverse sin. In order to improve, you must practice more math problems.So we can use the law of cosines to find the length of the third side \$x\$. One of the other sides of the pen would be the m\$ wall of the barn which is at an angle of \$ degrees to the fence. The side \$BC\$ of this triangle is our barn wall which is m\$ long.A triangular pen for livestock is to be constructed in the back yard. Now we know that we have the length of two sides of the triangle and the measure of the included angle.
