Why is trigonometry important.

When learning about trigonometry, many students struggle to understand how it is relevant in real life.

Studying the properties of triangles and calculating missing angles can seem like an arbitrary task, but it actually has many applications in the real world. From astronomy, to aviation, medicine and more, trigonometry allows many industries to function.

## Essential Knowledge for Future Scientists

A solid knowledge of trigonometry is essential for any student who aspires to work in a scientific discipline.

Students will need to master trigonometry at GCSE level in order to study A-Level maths and sciences, subjects which they will need to secure a university place for engineering, medicine, and the sciences. Although many computer applications perform trigonometric calculations automatically, all the staff working in these industries will have an excellent knowledge of trigonometry and use it regularly.

## Nurture Students’ Transferable Skills

Even if students do not wish to pursue a career in these technical and scientific fields, practicing trigonometry questions helps them develop transferable skills valued by all employers.

Using Trigonometry improves students’ problem solving abilities and promotes critical thinking, skills which will prove useful throughout their studies and into adult life. Providing students with trigonometry worksheets helps to nurture these skills, allowing them to be successful not just at their maths exams but right the way through their career.

## We use trigonometric ratios, especially for the measurements of a right triangle. In a right triangle, two sides that make the right angle, we call them legs. The side that is opposite to the right angle is called the hypotenuse. Only three trigonometric ratios are Sine, Cosine, Tangent. To solve the triangle, we have the following formulas; Sine = length of the leg opposite to the angle/length of the hypotenuse (Abbreviated Sin). Cosine = length of the leg adjacent to angle/length of the hypotenuse (Abbreviation Cos). Tangent = length of the leg opposite to the angle/length of the leg to the angle (tan). We have a triangle A.B.C. C.B. is the right angle, B.A. is the hypotenuse, and C.A. is the base. Find angle A. Opposite angle A, the length of a leg is (a). Adjacent to angle A, the length of the leg is (b), and the length of the hypotenuse is (c). The ratio opposite over hypotenuse is the Sine of the angle like; Sin angle A = a/c. The ratio adjacent over hypotenuse, the cosine is; Cos angle A = b/c. The ratio opposite over adjacent, the tangent is; Tan angle = a/b.

For a right triangle, there are six trigonometric ratios: sine, cosine (cos), tangent, cosecant, secant, and cotangent. In these worksheets, students will be working primarily with sine. Your students will be given the value of sides and/or angles of a triangle, and they will then calculate the missing value of a specified side, or the missing value of a specified angle. Diagrams of each triangle the student will be working with are provided as visual aids. Students may require extra paper for their calculations. This set of worksheets contains step-by-step solutions to sample problems, both simple and more complex problems, a review, and a quiz. Problems are also provided for students to practice independently. When finished with this set of worksheets, students will be able to solve problems using trigonometric ratios. These worksheets explain how to use trigonometric ratios to find the missing value of a triangle. Sample problems are solved and practice problems are provided.

- Your calculator should read 0.574 . If you do not get the correct answer, check to make sure that your calculator is in degree mode .
- Type 12 into your calculator
- press the cos button.
- Your calculator should read 0.978 .
- Type 75 into your calculator
- press the tan button.
- Your calculator should read 0.0879 .

- Depending on your calculator, you will typically need to press a button labeled 2 nd (sometimes shift) on your calculator and then the sin button. This produces sin -1 on the calculator screen.
- Enter 0.5 after the sin -1 .
- Hit enter or = and the result should be 30 degrees .
