Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...

Here's another example to work through. This time you need to draw two right-angled triangles to help you with your working. If \(\sin p = \frac{3}{5}\) and \(\tan q ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...

The chapter Trigonometric Functions is a very important part of Mathematics in the syllabus of JEE Examination 2018. In this article, you will get chapter notes of chapter Trigonometric Functions ...

Using a relationship derived from a special case of DeMoivre's Theorem, we can express the sine and cosine functions as infinite series of generalized binomial coefficients. We will derive these ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.
