"Khan Academy Solve For A Side In Right Triangles" ~ bbaz
One of the most important concepts in trigonometry is the use of right triangles. It helps us solve a wide variety of problems. One of these important problems is to find the length of a side given the measure of other sides and/or angles. This process is called solving for a side in a right triangle.
Khan Academy and Solving for a Side in a Right Triangle
Khan Academy is an online learning platform that offers educational resources across many subjects including math and science. When it comes to geometry, trigonometry, and algebra, Khan Academy has been an excellent source of study material. Their lessons are self-paced which means students can learn at their own speed and watch video demonstrations and solve problems without additional help from a teacher.
Solving for a side in a right triangle is one of the key skills that students will learn through Khan Academy's Algebra Based Physics course. This course covers the basics of algebraic equations that are needed to understand physics principles and problems.
The Importance of Right Triangles in Trigonometry
Trigonometry is the study of relationships between angles and sides of triangles and is used throughout mathematics, science, and engineering. In trigonometry, we use right triangles because they are easy to work with and have properties that make calculations easier. One of the most important properties of right triangles is the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. This theorem can be used to find the length of any side of a right triangle.
Solving for a Side in a Right Triangle
There are three sides in a right triangle: the hypotenuse and two legs. The longest side of a right triangle is always the hypotenuse. The other two sides are called legs. Solving for a side in a right triangle means that given one or two sides, the student can find the length of another side.
The basic idea behind solving for a side in a right triangle is to use one of the following trigonometric functions: sine, cosine or tangent. These functions represent the ratio of two sides of a triangle and are used to find missing sides and/or angles.
The sine, cosine, and tangent functions all relate the lengths of two sides of a right triangle to one of its angles. Its reciprocal functions, cosecant, secant, and cotangent, are then used to solve for the other sides.
Solving for a Side using Sine, Cosine and Tangent Formula
For example, let's say that we want to solve for the length of side a of a right triangle where angle A is known and the length of the hypotenuse c is also known. We can use any of the following formulas:
- Sine: sin(A) = a/c, a = c*sin(A)
- Cosine: cos(A) = b/c, b = c*cos(A)
- Tangent: tan(A) = a/b, a = b*tan(A), or b = a/tan(A)
If we know the length of one of the legs and want to solve for the other leg, we can still use the sine, cosine, or tangent formula, but we need to use a different ratio. Here's an example:
Let's say that we want to solve for the length of side b of a right triangle where angle B is known and the length of the hypotenuse c is also known. We can use any of the following formulas:
- Sine: sin(B) = b/c, b = c*sin(B)
- Cosine: cos(B) = a/c, a = c*cos(B)
- Tangent: tan(B) = b/a, b = a*tan(B), or a = b/tan(B)
Solving for a Side using Cosecant, Secant and Cotangent Formula
If we want to find the length of the hypotenuse given the lengths of the two legs, we can use the Pythagorean theorem. If we want to solve for a side and don't know the angle between the known sides, we need to use more advanced formulas like the Law of Sines or the Law of Cosines.
The reciprocal functions, cosecant, secant, and cotangent, are used to solve for the other sides. They are defined as follows:
- Cosecant: csc(A) = 1/sin(A)
- Secant: sec(A) = 1/cos(A)
- Cotangent: cot(A) = 1/tan(A)
The next step is to plug in the known values into these equations and solve for the unknown values. Here's an example:
Let's say that we want to solve for the length of the hypotenuse c of a right triangle where angle A is known and the length of one of the legs, a, is also known. We can use the following formula:
c = a/cos(A)
Now, we can use Khan Academy to practice similar problems and work through examples until the concept is mastered.
Conclusion
Solving for a side in right triangles is an important part of geometry and trigonometry. Khan Academy has provided students with an excellent online resource that teaches this concept and provides students a self-paced learning environment. Solving for a side in a right triangle does not have to be complex, and once the basic principles are understood, advanced formulas can be utilized.
