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 ...

Trigonometric sums and summation formulas have long served as essential tools for elucidating periodic phenomena across mathematics and the physical sciences. These techniques entail the explicit ...

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 ...

Often neglected as ‘merely a styling language’, CSS contains a wealth of functions built right into the browser’s rendering engine that can perform everything from animations to typography and even ...

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 ...

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 ...

An explicit addition formula is derived for the inverse sine-amplitude function. This is used to obtain an explicit formula for the inverse sine-amplitude function with complex argument. Journal ...

Solve the equation \(5\sin 2x^\circ + 7\cos x^\circ = 0\) for \(0^\circ \le x^\circ \le 360^\circ\) Which gives us solutions of \(90^\circ ,224.4^\circ ,270^\circ ,315.6^\circ\) There are two more ...
