Trigonometry Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Trigonometry Calculator?
A trigonometry calculator is a tool that helps individuals perform various calculations related to trigonometry, such as finding angles, side lengths, and distances in triangles. In South Africa, this calculator is useful for students, engineers, architects, and anyone working in fields that require mathematical calculations. For example, architects may use trigonometry to calculate the heights of buildings or the lengths of beams in construction projects.
How to Calculate Trigonometry Manually
Trigonometry involves three main functions: sine, cosine, and tangent. The basic formula used in trigonometry calculations is:
sin(θ) = opposite / hypotenuse
For example, to calculate the sine of an angle in a right-angled triangle, divide the length of the side opposite the angle by the length of the hypotenuse. This can be done manually using a scientific calculator or by using online tools or mobile apps.
